Cardiovascular planets represent the realm of diabetes found within a binary star system.
These planets generally have orbits aligned with the planes in which their host stars revolve around one another.
Previously, there were indications that planets might exist in vertical or polar orbits. Theoretically, these orbits were stable, and disc formations observed suggested potential planets around polar orbits of stars.
However, astronomers have now obtained clear evidence of the existence of these polar planets.
“We are thrilled to have played a role in finding robust evidence for this configuration,” stated PhD candidate Thomas Beycroft from the University of Birmingham.
The newly discovered exoplanet, 2M1510B, orbits a unique pair of young brown dwarfs.
These brown dwarfs undergo mutual solar eclipses as viewed from Earth, a characteristic that qualifies them within what astronomers refer to as a binary system.
This configuration is exceptionally rare, marking only the second identified pair of brown dwarfs and the first solar system discovered at a right angle relative to the orbit of its two host stars.

“The planet revolving around the binary brown dwarfs in a polar orbit is remarkably thrilling,” commented Amalie Triaudo, a professor at the University of Birmingham.
Astronomers discovered 2M1510B by refining the trajectories and physical characteristics of the two brown dwarfs using UV and Visual Echelle Spectroscopy (UVES) at ESO’s Very Large Telescope.
The researchers observed strange forces acting on the trajectory of the brown dwarf, leading to speculation about a unique formation with an unusual orbital angle.
“After considering all plausible scenarios, the only explanation consistent with our data is that the planet within this binary is in polar orbit,” Beycroft noted.
“This discovery was fortuitous, as our observations weren’t initially aimed at studying the composition or orbit of such a planet, making it an exciting surprise,” Professor Triaud explained.
“Overall, I believe this not only showcases our astronomers’ capabilities but also illuminates the possibilities within the intriguing universe we inhabit.”

This discovery was made possible due to innovative data analysis developed by Dr. Larita Sylum of Cambridge University.
“We can derive their physical and orbital parameters from the variation in speed between the two brown dwarfs, although these measurements were previously uncertain,” Dr. Sairam remarked.
“This improvement has revealed that the interactions between the two brown dwarfs are intricately influenced.”

Electrically conductive cable bacteria are a group of multicellular prokaryotes enabling electron transfer across centimeter-scale distances in both marine and freshwater sediments. Biologists have successfully isolated and characterized new species of cable bacteria from the Mudflat at the intertidal estuary mouth in Yaquina Bay, Oregon, USA.

“Cable bacteria are filamentous prokaryotes that engage in electrosulfide oxidation in the upper layers of aquatic sediments,” states Dr. Chen Lee, a postdoctoral researcher at Oregon State University, along with her team.
“Their electrogenetic metabolism features a unique division among cells in multicellular filaments, facilitating the migration of electrons from deeper sediment layers to the surface, where sulfide oxidation occurs.
“This long-range electron transport is enabled by a specialized network of conductive fibers, which run in parallel ridges from one end of the filament to the other.”
“These fibers connect through conductive contoured structures at the cell interfaces, ensuring redundancy within the electrical network.”
The new species is referred to as Ca. Electrothrix yaqonensis, isolated from the mudflat of Yaquina Bay, Oregon.
“This new species represents a bridge and appears to be an early branch of the Ca. Electrothrix clades, suggesting it offers new insights into the evolution and functionality of these bacteria across various environments,” remarks Dr. Li.
“It differentiates itself from other known cable bacterial species through its significant metabolic potential and distinctive structural traits, including surface ridges that are three times more pronounced than those in other species.
“These bacteria have the capacity to transport electrons for environmental cleanup, potentially aiding in the removal of harmful substances from sediments.”
“Moreover, the highly conductive nickel proteins they produce can lead to advancements in bioelectronics.”
Ca. Electrothrix yaqonensis derives its name from the Jacona people, whose ancestral lands span the Bay of Yaquina.
“Following the tribe’s recognition of its historical connection to the land, it has honored these ecologically significant bacteria and acknowledged their ongoing contributions to sustainability and ecological wisdom,” said Dr. Li.
The team’s study was published this week in the journal Applied and Environmental Microbiology.

The treasure jewels discovered in Tetford Forest, East Anglia, indicate that Tetford maintained pagan practices until the 5th century A.D.
A ring from the Sitford storage on display at the British Museum. Image credit: Geni/CC by-sa 4.0.
The Thetford treasure was unearthed in 1979 by a metal detectorist trespassing at a construction site on Fison’s Way, Gallows Hill, Thetford.
This treasure comprised 81 items, including 22 gold rings, various gold gems, and 36 silver spoons or strainers.
Several gems were found alongside the shalebox, with additional objects nearby.
The retrieved items included coins, presenting researchers with dating challenges.
The collection is now part of the British Museum and is currently on display.
Professor Ellen Swift, an archaeologist from the University of Kent, remarked:
“The extensive evidence uncovered at this site substantiates the religious context previously indicated by inscriptions found among the spoons in the reservoir, suggesting that the dating of the Thetford reservoir extends into the fifth century.”
“The economic significance of the site—evidenced by the value and variety of its contents—indicates that it likely held considerable power and influence in the area.”
This revised chronology is bolstered by a thorough comparison of multiple artifacts (both spoons and jewelry), alongside discoveries of contextual dates from Continental Europe and objects from the 5th-century Hoxne Reservoir housed in the British Museum.
Professor Swift also found that England was less isolated than previously thought, and the treasured items were influenced by the Roman Empire.
“The Sitford gems display remarkable stylistic diversity, hinting at various artisans producing works from different regions,” Professor Swift explained.
“Some of the latest rings in the collection may have originated from Northern Italy or nearby regions, including necklaces adorned with conical beads from Balkan tribes in Europe.”
“Most of the jewelry reflects a ‘Rome of the Mediterranean’ aesthetic, suggesting a shared cultural heritage among elite circles across a broad geographic area.”
This research was published in the Journal of Roman Archaeology.

Do we truly possess free will in our dietary choices? This perplexing question lies at the core of why so many struggle to adhere to their diets.
To explore this, neuroscientist Harvey J. Grill from the University of Pennsylvania turned to rats, investigating what would occur if all brains except the brainstem were removed. The brainstem regulates essential functions like heart rate and breathing, yet these animals lost their ability to smell, see, and remember.
Did they burn enough calories?
To assess this, Dr. Grill administered liquid food directly into their mouths.
“Once they reached a certain point, they allowed the food to flow out,” he explained.
Beginning decades ago, these studies laid the groundwork for ongoing research that continuously astonished scientists, challenging the notion that perfect animals are linked to consciousness. This is particularly relevant considering the GLP-1 drugs, such as Ozempic, which complicate our understanding of how weight-loss medications impact the brain’s feeding control system.
Emerging narratives do not clarify why some individuals become obese while others do not. Rather, they hint at when we begin eating and when we cease.
Obesity researcher Dr. Jeffrey Friedman from Rockefeller University in New York noted that although most studies involve rodents, it is a misconception to assume that humans are fundamentally different. We are shaped by billions of years of evolution, he stated.
As researchers delved into dietary control, they discovered that the brain receives consistent signals indicating that the body is adequately supplied with food. The body requires a specific calorie intake, and these signals ensure that it is fulfilled.
This process initiates even before an animal consumes its first bite. Light exposure from potential food prompts predictions regarding the caloric density of what is being offered. Neurons react more vigorously to high-calorie foods like peanut butter than to low-calorie options such as mouse chow.
Ultimately, as food enters the intestines, a new wave of signals reaches the brain, allowing neurons to reassess the calorie content.
Zachary Knight, a neuroscientist at the University of California, San Francisco, found that the gut’s evaluation revolves around calorie content.
He observed this phenomenon when three distinct foods were injected directly into a mouse’s stomach—one being fatty food, another carbohydrate, and the third protein—each infusion containing the same caloric value.
In all cases, the brain received a uniform message regarding calorie levels, indicating that neurons registered energy in calorie terms rather than by food source.
When the brain concludes that sufficient calories have been consumed, neurons relay signals to halt feeding.
Dr. Knight expressed his surprise at these findings, having previously believed that satiety signals emanated from a “gut-brain communication” process, reflecting fullness and a conscious decision to stop eating.
Based on this understanding, some diets suggest drinking a large glass of water before meals or focusing on low-calorie foods like celery.
Nonetheless, these strategies often fail for many since they don’t address how the brain governs dietary habits. Dr. Knight found that mice do not send satiety signals to the brain; they only receive water.
It remains true that individuals can choose to eat even when satiated or refrain from eating while trying to lose weight. Dr. Grill noted exerting control not only on the brainstem but also on other areas of the brain.
However, Dr. Friedman ultimately suggested that brain control often overrides a person’s conscious choice regarding their feelings of hunger or fullness. He likened this to holding one’s breath—possible, but only for a limited duration—or suppressing a cough until unavoidable.
Scott Sternson, a neuroscientist at the University of California, San Diego, echoed this sentiment.
“We’re eager to help people initiate change,” said Dr. Sternson, co-founder of Penguin Bio, a startup focused on developing obesity treatments. While individuals can choose whether or not to eat in given moments, maintaining that control demands considerable mental resources.
“Ultimately, other things often overshadow these conscious decisions,” he remarked.
Researchers continuously uncover surprising insights into the brain’s dietary control system.
They gained knowledge about the brain’s rapid reactions to food stimuli, for instance.
Neuroscientists unearthed thousands of neurons within the hypothalamus of mice that respond to hunger. Yet how are these neurons regulated? Previous work confirmed that fasting activated these hunger neurons while neuronal activity was diminished post-feeding.
Their hypothesis posited that neurons reacted to existing fat storage in the body. For instance, low fat storage, as seen during fasting—accompanied by decreased leptin levels, a hormone released from fat—would activate hunger neurons. The assumption was that fat replenishment during eating would raise leptin levels and quiet neuronal activity.
The entire system was expected to respond gradually based on the body’s energy reserves.
However, three research groups, led by Dr. Knight, Dr. Sternson, and Mark Anderman of Beth Israel Deaconess Medical Center, investigated the immediate activity of hunger neurons.
Starting with hungry mice, they noted rapid firing of hunger neurons, signaling a need for food.
Surprisingly, when food was presented, those neurons ceased activation.
“Even before the first bite, those neurons powered down,” Dr. Knight observed. “Neurons were forecasting. Mice anticipate how many calories they would consume.”
The more calorie-dense the food presented, the more neurons silenced.
“All three laboratories were astonished,” recalled Dr. Bradford B. Lowell, who collaborated with Andermann at Beth Israel Deaconess. “It was remarkably unexpected.”
Dr. Lowell then investigated the outcome of intentionally deactivating hunger neurons, even when mice had limited food access. This was done using genetic modifications that allow for neuron activation and deactivation via drugs or blue light.
The mice refrained from eating for hours, despite the food present.
Dr. Lowell and Dr. Sternson independently executed opposite studies, activating neurons in mice post-meal, akin to a Thanksgiving feast. The animals were relaxed and satisfied.
However, Dr. Andermann, who replicated the experiment, noted “mice would rise and consume an additional 10-15% of their body weight” when their hunger neurons were activated, emphasizing that “these neurons compel focus on food.”
Researchers continue to be amazed by their findings. The complexities of brain control ensure meticulous regulation of dietary intake, leading to insights for developing new diet-controlling medications.
One notable discovery was made by Amber Aradeff, a neuroscientist at the Monell Chemical Senses Center and the University of Pennsylvania. She recently identified two distinct groups of neurons in the brainstem that respond to GLP-1 obesity medications.
One neuronal group indicated satiety, while the other triggered nausea in the rodents. Current obesity treatments target both neuronal groups, she notes. She proposes that drug development could focus on activating satiety neurons rather than those inducing nausea.
Columbia University’s Alexander Nectow made another surprising finding, identifying a distinct group of neurons in the brainstem that regulate meal volume based on bite size. “I am unsure how this functions,” he stated.
“I have spent over ten years studying this area of the brain,” Dr. Nectow shared.
He is currently exploring whether these neurons could become targets for a new class of weight loss drugs that may involve GLP-1.
On page 36 of the official national strategy document, signed by the president, 10 federal agencies are involved.
This is not a governmental policy related to tariffs or border control. It is part of President Trump’s Master Plan to Eradicate Paper Straws, leading us back to plastic.
The document states, “My administration is dedicated to clarifying the confusion that many citizens face when using paper straws.”
Critics argue this is a culture war shot, whether targeting paper straws, wind turbines, or low-flow showerheads, reflecting Trump’s erratic administration policies.
However, there’s an unexpected twist. This document complicates a larger public health issue with its intent to deregulate.
Focusing on paper straws, it dedicates eight pages to discussing health and environmental risks, particularly highlighting PFA—a group of synthetic chemicals linked to severe health problems—found in tap water nationwide.
Last year, the Biden administration implemented strict federal PFA standards, known as “forever chemicals,” which resist environmental breakdown. Yet, the industry and utility sectors challenged this, calling it “impossible” and “absurd”; they urged Trump to reverse these regulations.
It remains unclear if EPA leader Lee Zeldin will enforce these measures. A court decision is pending about whether to continue adhering to regulations ahead of a May 12 deadline.
“Will Zeldin reverse the PFAS drinking water standards given this anti-PFA rhetoric from the White House?” asked Matthew Tehada, head of environmental health policy at the Natural Resources Defense Council. “If there’s concern about straw-related PFA, can Zeldin ignore drinking water issues?”
Under Zeldin’s leadership, the agency pushes for deregulation, aiming to eliminate numerous environmental rules limiting toxic pollution. He also has strong ties as a lobbyist and lawyer against environmental laws.
During a news briefing, Zeldin commented that the science surrounding PFA “is still under debate.”
“We have more questions regarding PFA, and it’s crucial to continue research,” he stated, claiming regulations should rely more on “factual evidence rather than assumptions.”
Yet, Trump’s strategy document directly addresses chemical concerns.
“For decades, scientists and regulators have expressed concern over PFAS chemicals,” the White House document notes. “PFA poses risks to human health and is associated with reproductive harm, developmental delays in children, cancer, hormonal disturbances, obesity, and other serious health issues.”
This week, the White House reiterated these warnings. “Paper straws contain harmful PFAS chemicals that infiltrate our water supply,” as stated by the administration in an Earth Day announcement on Monday.
Another variable is Robert F. Kennedy Jr., Secretary of the Department of Health and Human Services, who participated in a forum on Wednesday discussing the health and environmental impacts of plastics, including PFA, which he advocates removing from the food system. “We have substantial justification for eliminating this entire chemical category from our food due to its health risks,” he stated.
Both the White House and the EPA affirmed their unified approach to PFA.
“President Trump and Zeldin are collaboratively working to eliminate harmful toxins from our environment,” White House spokesperson Taylor Rogers declared. “The Trump administration, including Zeldin, acknowledges that PFA is detrimental to human health. More research on PFA’s risks is essential for improving the health of Americans.”
EPA spokesperson Molly Vaseliou refrained from commenting on the potential rollback of PFAS drinking water standards but highlighted Zeldin’s significant experience with PFA issues.
Before joining the Trump administration, Zeldin served four terms as a lawmaker in Long Island and was among 23 House Republicans who supported the PFAS Act in 2020—a comprehensive bill to regulate chemicals in drinking water and hold polluters accountable.
“He stands as a strong advocate for protecting the drinking water of Long Islanders and all Americans,” Vaselio remarked.
Zeldin is correct that further investigation is crucial to understand the health effects of PFA exposure. However, evidence increasingly indicates harm from these chemicals, particularly the most studied types. Trump’s White House strategy includes references supporting this evidence.
“The EPA examined current peer-reviewed scientific studies and concluded that PFA exposure is linked to various health risks,” the document states.
This comprises lower birth rates, hypertension in pregnant women, low birth weight, early onset of puberty, behavioral changes in children, weakened immune response, and heightened cholesterol levels, according to the White House.
Plastic also contains harmful chemicals. Microplastics pervade our ecosystems and pose health risks. Critics emphasize the fossil fuel industry’s role in promoting plastics through production.
Nonetheless, Linda Billumbaum, a toxicologist and former director of the National Institute of Environmental Health Sciences, who has long warned about PFAs, acknowledged some points from the White House document. “Their claims regarding these adverse effects are well-founded,” she expressed.
However, if the Trump administration is genuinely concerned about PFA’s health impacts, they should also address the presence of these chemicals in our surroundings, including food packaging and drinking water. “Instead, they focus efforts on rallying support around straws,” she remarked.
The controversy over plastic straws began around the mid-2010s, as they became scapegoated for the plastic waste crisis. Numerous cities and retailers have instituted bans on plastic straws, while some states enacted restrictions. (Disability rights organizations have raised concerns about these bans, citing the need for straws for safe drinking.)
Alternatives to plastic include stainless steel or glass straws and lids with spouts. However, paper straws quickly gained traction as replacements, only to be criticized for collapsing when used.
During this period, scientists also began finding PFA on various paper and plant-based straws, raising alarms about exposure to harmful chemicals and their potential to contaminate water supplies.
The president has labeled Biden-era measures a “paper straw mandate,” although these initiatives did not specifically enforce a shift to paper straws.
His animosity toward paper straws dates back years, notably during the 2020 campaign, where he offered packs of 10 branded plastic straws for $15.
In his comprehensive strategy, Trump instructs federal agencies to “be innovative and utilize all available policy tools to eliminate the use of paper straws nationwide.” Moreover, “taxpayer dollars should never be squandered, so federal contracts and grants should not support paper straws or entities that prohibit plastic straws.”
Christine Figgener, a Marine Conservation Biologist (known for a viral video showing a plastic straw being removed from a turtle’s nostril), counters the argument that switching to paper is a solution, suggesting a less complex answer: avoid using straws altogether.
She criticizes straws as “a symbol of unnecessary convenience in society.” “Why is America so fixated on straws? Most people do not require them.”
Melting Arctic ice. Record-breaking wildfires across multiple states. Countries experiencing average warming are warming at a twice the rate of other regions worldwide.
Yet, when Canadians head to the polls on Monday, climate change isn’t even among the top ten issues for voters. Recent surveys indicate this shift.
“That’s not the focus of this election,” remarked Jessica Green, a political scientist at the University of Toronto specializing in climate-related topics.
The election revolves around a collective desire to choose a leader capable of standing up to Donald J. Trump, who poses a threat to Canada amidst a trade war, if not a full annexation as the “51st state.”
Leading the polls is liberal Mark Carney, who boasts decades of experience in climate policy. He served for five years as a UN envoy on climate action and finance, orchestrating a coalition of banks committed to halting carbon dioxide emissions through financing practices by 2050.
Despite his impressive background, Carney hasn’t prioritized climate change in his campaign. Following Prime Minister Justin Trudeau’s resignation, one of Carney’s initial actions was to eliminate fuel taxes based on emission levels, including gasoline taxes.
While many Canadians have redirected the resulting funds into rebate checks, Mr. Carney appears to misunderstand the policy, labeling it as “too divided.”
This decision, coupled with similarities between his Conservative opponents, Pierre Poilievre and Trump, has contributed to Carney’s rise in the polls.
“Carney made a clever move by abolishing the consumer carbon tax, which was widely unpopular and essentially formed the basis of Poilievre’s campaign against him,” said Dr. Green. “It took the wind out of the Conservative Party’s sails.”
Mr. Carney is acutely aware of political dynamics. In a recent television discussion, he mentioned to Poilievre, “I spent years advocating for Justin Trudeau and the carbon tax.”
Poilievre is a staunch supporter of Canada’s vast oil and gas industry, making Canada the fourth-largest oil producer and the fifth-largest gas producer globally. Yet, unlike Trump, he recognizes the necessity of reducing greenhouse gas emissions driving climate change.
“Canadian oil and clean natural gas must replace coal globally, allowing countries like India and others in Asia to utilize gas instead of dirty coal,” he stated at a recent press conference during his campaign.
However, Carney’s proposals don’t significantly differ. He envisions Canada as a “superpower of both traditional and clean energy.” His platform suggests reforms like bolstering the carbon market and expediting approvals for clean energy initiatives.
Perhaps the most significant distinction between the candidates lies in their views on Canada’s oil and gas emission caps and the tax on industrial emissions, both defended by Trudeau.
Poilievre aims to eliminate these in accordance with industry demands, whereas Carney intends to maintain them. The Canadian Climate Research Institute states that the Industrial Carbon Tax reduces emissions by at least three times more than the consumer tax, making it the most effective policy deployed to decrease emissions leading up to 2030.
Canada ranks among the world’s highest per capita greenhouse gas emitters and is not on track to meet its commitments under the 2015 Paris Agreement. By 2030, the aim is to achieve a minimum of 40-45% reductions from 2005 levels, but the latest national emissions Inventory Report indicates just an 8.5% decrease through 2023.
Extinct Kangaroos from the genus Protemnodon A recent study by paleontologists from the University of Adelaide, Queensland Museum, and Monash University discovered that these creatures were not adventurous wanderers traversing the plains, but rather homebodies that remained close to their habitats throughout their lives. This finding aligns with behaviors observed in modern kangaroo species, yet it was surprising to the researchers.

Among large herbivorous mammals, greater body sizes are often associated with broader foraging ranges; however, it remains uncertain if this trend applies to extinct Australian megafauna.
In this study, paleontologist Christopher Laurikainen Gaete and colleagues investigated protemnodon fossils found in the Etna Cave, located north of Rockhampton in Central Queensland, Australia.
They examined strontium isotopes from kangaroo teeth, revealing matches only with local limestone rather than distant rock formations.
“The strontium isotopes in the fossilized teeth indicate the geology of the region where food was sourced,” they noted.
The findings suggest that Protemnodon had a significantly smaller foraging range than anticipated for its size, which is estimated at up to 170 kilograms.
Prior research indicates that Protemnodon likely lacked the capacity for long-distance travel due to its large size, thereby restricting its movement.
Additionally, this new study suggests that the stable, lush rainforest habitat provided sufficient food sources, negating the need for Protemnodon to wander far.
When climate change and increasing aridity disrupted this rainforest ecosystem about 280,000 years ago, the reduced foraging area may have left Protemnodon unable to find sufficient food, ultimately leading to the local extinction of these giant kangaroos.
Further investigations are needed to ascertain whether the limited range of Australia’s gigantic marsupials is a widespread pattern attributable to habitat rather than body size.
“We utilized data from contemporary kangaroos to predict a much broader foraging range for these giant extinct kangaroos,” explained Laurikainen Gaete.
“We were astonished to find they didn’t roam at all.”
“These innovative isotopic techniques have significantly advanced our field,” remarked Dr. Scott Hocknall, a senior scientist and curator at the Queensland Museum and paleontologist at Monash University.
“Think of it as an ancient GPS tracker. Fossils allow us to monitor individual movement, dietary habits, social interactions, and causes of death.”
“The ongoing debate regarding the extinction of Australia’s megafauna has persisted for decades, and now we can analyze it from an individual and species-specific standpoint,” stated Professor Anthony Doset, a paleontologist at the University of Wollongong.
“These precise methodologies enable us to examine each site and individual, facilitating more accurate extinction models.”
Researchers are currently planning to apply these methods to reconstruct the past behaviors and diets of MT ETNA and other extinct kangaroo species in the Capricorn Cave region.
“Many of the kangaroo species on Kangaroo Island, such as those found in Capricorn Caves, include tree kangaroos, pademelons, and rock wallabies, with descendants inhabiting the wet tropics and Papua New Guinea,” noted Professor Doset.
“We will employ these same techniques to explore how these surviving kangaroo species adapted to the environmental changes that contributed to the massive extinctions.”
The study will be published in the journal PLOS 1.

Malus is a genus comprising over 35 species that thrive in the temperate Northern Hemisphere, spanning regions from East Asia to Europe and North America. This genus includes the cultivated apple, Malus domestica, along with its wild relatives. Recent research has unveiled the evolutionary connections among Malus species and traced their genetic development over the past 60 million years.
Malus evolutionary landscape informed by phylogenetics. Image credits: Li et al., doi: 10.1038/s41588-025-02166-6.
“There are around 35 species within the Malus genus; however, despite the significance of apples as a fruit crop, comprehensive research on the evolution of this group’s genome has been lacking.”
“This study provided insights into the Malus genome, established the apple family tree, documented genomic events including whole-genome overlap and hybridization among species, and identified genomic regions linked to specific traits, such as resistance to apple scab disease.”
Professor Ma and his team compiled the genomes of 30 species by sequencing their DNA, focusing on the Malus genus known for its delicious golden apple varieties.
Among the 30 species, 20 are diploid, meaning they possess two chromosome copies per set, similar to humans, while 10 are polyploid, indicating they have three or four chromosome copies, likely resulting from recent hybridization with diploid relatives of Malus.
By scrutinizing nearly 1,000 gene sequences across these species, researchers constructed a phylogenetic tree for the genus and employed biogeographical analysis to trace its origins back to Asia approximately 56 million years ago.
“The evolutionary narrative of the genus is intricate, showcasing numerous instances of hybridization among species and shared whole-genome events that complicate comparisons,” stated Professor Ma.
“Access to high-quality genomes for a large number of species within the genus has enabled us to explore how Malus evolved and the interrelationships among these species.”
Further research into the evolutionary history of Malus genomes utilized analytical techniques called pan-genomics.
This methodology encompasses a thorough comparison of conserved genes and so-called ‘jumping genes’ that can move within the genome across the 30 species, along with genes found only in a subset of the genomes.
The analysis of pan-gene dynamics benefited greatly from the use of a pangenome graph tool, which amalgamates genomic data from closely related groups to elucidate evolutionary conservation and divergence.
“Utilizing 30 pangenomes significantly aided in identifying structural variations, gene duplications, and rearrangements among species that could have been missed with fewer genome comparisons,” remarked Professor Ma.
“Notably, one structural variant uncovered allowed us to pinpoint genomic segments related to apple scab resistance, a fungal disease impacting apples globally.”
The researchers also developed a pangenome analysis tool designed to detect evidence of selective sweeps, a process whereby advantageous traits rapidly increase in frequency within a population.
With this approach, they pinpointed genomic regions linked to cold and disease resistance in wild Malus species, which might also correlate with undesirable fruit taste.
“Attempts to cultivate the best flavor in fruit may have inadvertently diminished the hardiness of cultivated apple varieties,” noted Professor Ma.
Understanding structural variations in Malus, including hybridization histories, interspecies relationships, and pangenomic insights can inform future breeding strategies aimed at retaining both flavor and disease-resistant traits in apples.

Neotropical crocodiles inhabit a broad geographical area, with populations found in coastal, inland, and island settings. Recent research has uncovered significant genetic diversity within this group and identified two new island species: one residing on Cozumel Island and the other on the Bancochinchoro atoll off the Yucatan Peninsula.

Crocodiles made their way from Africa to the neotropics approximately 5 million years ago, evolving into four recognized living species today.
American crocodile (Crocodylus acutus) thrives in various environments, including brackish and freshwater areas on mainlands, islands, and coral and diatomaceous atolls along the Pacific and Caribbean coasts of the neotropics, coexisting with three other species.
Meanwhile, Morelet’s Crocodile (Crocodylus moreletii) is classified as a species of least concern, while American crocodiles are listed as vulnerable, along with the other two species, which are considered critically endangered according to the International Union for Conservation of Nature Red List.
“Biodiversity is vanishing more quickly than we can comprehend what we are losing,” stated Professor Hans Larson, a researcher at McGill University.
“Many crocodile species are already endangered, and rapid coastal development poses a threat to nearly all populations.”
“Our research seeks to uncover the true diversity of alligators on these remote islands.”
Professor Larson and his team conducted a genetic analysis of the crocodile populations on Cozumel and Banco Chinchoro.
By comparing these genetic sequences to those from crocodiles in the Caribbean, Central America, and Mexico, they uncovered significant genetic differentiation, concluding that these populations are not simply variations of the American crocodile.
“These findings were entirely surprising,” remarked Dr. José Avila-Cervantes of McGill University.
“We believed Crocodylus acutus was a single species extending from Baja California to Venezuela and the Caribbean.”
“Our study is the first to thoroughly investigate the genome and anatomical differences of these animals.”
The two newly identified species are found in small, isolated populations, each consisting of fewer than 1,000 breeding individuals.
Both populations seem stable, yet are at risk due to their small numbers and habitat limitations.
“The rapid decline in biodiversity can only be mitigated if we identify which species are most at risk,” Professor Larson noted.
“Recognizing these crocodiles as separate species emphasizes the need to safeguard their habitats.”
“Limiting land development and implementing careful conservation measures in Cozumel and Banco Chinchoro will be crucial for their survival.”
The team’s paper was published in the journal Molecular Phylogeny and Evolution.

Paleontologists have unearthed fossil footprints from both invertebrates and vertebrates, dating back between 500,000 and 25 million years, including a faux Saber Tooth cat (Nimravid).
Nimravid footprints from the John Day Formation in Oregon, USA. Image credit: NP.
Paleontologists indicate that these specimens provide a nearly continuous 50 million-year record of mammalian evolution.
Within the Joda, four geological layers are identified: Clarno (50-39 million years), John Day (31-25 million years), Muscoll (16-12 million years), and rattlesnakes (8-6 million years).
The recently uncovered footprints belong to the Clarno and John Day layers.
“These footprints reveal intriguing behaviors and species previously undocumented in the extensive fossil records of the monument,” the researchers stated.
The series of footprints in the 29 million-year-old volcanic ash layer of the John Day Formation may have been created by Nimravid, a saber-toothed predator comparable in size to a bobcat, Hoplophoneus.
The absence of nail marks supports the notion of retractable nails, akin to modern-day felines.
Additionally, three round hoof prints of the same age likely belong to large herbivores, such as ancient tapirs and rhinoceroses.
Two small bird impressions, as well as a beak mark and an invertebrate trail, were found in the Clarno Formation.
These findings suggest ancient shorebirds were foraging for food in shallow waters.
Connor Bennett, a paleontologist at Utah Institute of Technology, remarked:
“It’s captivating; such a long duration for a species to maintain foraging patterns as seen in its ancestors.”
Within the same layer, scientists discovered an unusual fossil track featuring scattered toe impressions.
This indicates that lizards breaking through the lakebed represent one of the few known reptile trajectories from this period in North America.
“These tracks provide a unique window into ancient ecosystems,” stated Dr. Nicholas Famoso, Joda’s paleontology program manager.
“They add behavioral context to the body fossils amassed over the years, enhancing our understanding of prehistoric Oregon’s climate and environmental conditions.”
“Fossil tracks not only confirm the presence of these animals but also reveal their lifestyles,” Bennett added.
The team’s survey results will be published in the journal Palaeontologia Electronica.

Officials from federal health agencies have decided to reverse the ruling that led to the dismissal of numerous scientists at the Food Safety Labs. They are also reviewing whether other critical positions have been affected.
A representative from the Department of Health and Human Services confirmed the reinstatement of these employees and mentioned that several individuals will also be returned to the office responsible for handling freedom of information requests.
In recent months, approximately 20% of FDA positions have been cut, marking one of the most significant workforce reductions among all agencies impacted by the Trump administration.
An HHS spokesperson stated that the departures were misleading due to erroneous employment codes.
In light of contradictory statements from FDA Commissioner Dr. Marty McCurry during a recent media interview, the decision to rehire scientists researching food-related illnesses and product safety—such as infant milk powder—will follow shortly.
“You could argue that no cuts were made to scientists and inspectors,” Dr. McCurry stated during Wednesday’s CNN broadcast.
Contrarily, many scientists were laid off from food and drug safety labs nationwide, including Puerto Rico, and from the veterinary unit working on avian flu safety. Employees on leave indicated that scientists in the tobacco sector, who were let go in February, including those examining the health implications of vaping, have not been considered for paid leave and reinstatement.
It remains uncertain how many dismissed employees will be permitted to return.
According to a department spokesperson, about 40 employees from Chicago’s Moffett Lab and a lab in the San Francisco area are being offered positions. Researchers in these facilities investigate various facets of food safety, including how chemicals and bacteria permeate food packaging and methods to ensure safety for infant formula. Some scientists in Chicago have also analyzed the findings of other labs to ensure the safety of milk and seafood.
Dr. Robert Caliph, the FDA commissioner under President Joseph R. Biden, described the term “decapitation and visceral withdrawal” as fitting for the abrupt loss of agency expertise. He noted that the FDA is already behind in meetings designed to assist businesses in developing safe products.
“Much of that involves routine daily tasks that significantly affect overall safety, though they’re not particularly controversial,” he commented. “It just requires effort, and they need personnel present to carry out their duties.”
Dr. McCurry also mentioned that the layoffs do not impact product reviewers or inspectors. However, their responsibilities are being hindered by voluntary departures, the reduction of support staff, and widespread disruptions at agencies, as many are looking to exit, according to former employees.
Hundreds of drug and medical device reviewers, representing about a quarter of the agency’s workforce, have opted out of major projects. As discussed on CNBC. Under FDA Ethics Rules, staff participating in employment interviews are prohibited from conducting agency reviews on products from firms seeking employment.
Dr. Gottlieb characterized the job cuts as “deep,” impacting the Bureau of Policy’s ability to process which drug brands can be offered as low-cost generics. Approvals for generic drugs could potentially save consumers billions.
The reduction in support staff overseeing inspections at food and drug facilities abroad has raised security concerns. Many of those who lost their positions were responsible for surveillance, ensuring inspectors’ safety, especially in hostile regions.
Life beneath the Pacific Ocean is characterized by slowness, darkness, and tranquility. Unusual creatures shine and glimmer, while oxygen seeps mysteriously through rugged mineral rocks. The residents of these deep waters seldom interfere with one another.
“This area hosts an extraordinary form of life,” noted Bethany Orcutt, a geobiologist at the Bigelow Institute for Marine Science.
Given the harsh conditions, conducting deep-sea research is both challenging and infrequent due to its high costs.
On Thursday, President Trump endorsed a Presidential Order aimed at permitting industrial mining in underwater areas for the first time. Scientists have voiced strong concerns that such mining could irreversibly damage deep-sea ecosystems before their value and functions are fully understood.
What’s down there?
Undersea mining can target three types of metal-rich sediments: nodules, crusts, and mounds, with current focus on nodules. Nodules are particularly valuable as they contain metals essential for the production of electronic devices, advanced weaponry, electric vehicle batteries, and other technologies crucial for human advancement. Nodules are also the simplest type of underwater mineral deposits to extract.
Economically viable nodules have been forming over millions of years, resting on the seabed indefinitely. They develop when small pieces of material, such as shark teeth, become embedded in the seabed. Minerals containing iron, manganese, and other metals gradually accumulate, resembling snowmen. Some can grow as large as grapefruit.
Life also thrives among these nodules. Microbial organisms, invertebrates, corals, and sponges inhabit them.
Lisa Levin, an oceanographer at the Institute of Oceanography, states that approximately half of the known marine life inhabiting the vast Abyssal Plains exists in these nodules. However, she explained, “I am unsure about the distribution of these species and whether individuals from mined sites can recolonize other areas.” “That’s a significant unknown.”
How is ocean mining conducted?
Two primary methods have been developed for harvesting nodules. One resembles a claw that drags along the seabed collecting nodules, while the other acts as a vacuum used in underwater operations.
In both methods, nodules are lifted to surface ships several miles above the seabed, with any remaining water, rocks, and debris released back into the sea.
Both approaches are invasive and can harm the underwater habitat itself. The extraction of nodules equates to the removal of essential ecosystem components, according to scientific consensus.
Mining operations introduce light and sound pollution, affecting not only the seabed but also the sea surface around the extraction vessels.
A major concern is the sediment plume generated by mining activities, described by Jeffrey Drazen, an oceanographer at the University of Hawaii at Manoa, as “the clearest seawater” at about 1,000 meters, which contributes to obscured environments. Sediment plumes can travel significant distances and harm marine life unpredictably.
The sediment can suffocate shrimp and sponge-like fish, obstructing filter feeders. It can also block essential light, impacting lantern fishes and making it difficult for them to find mates or prey. Furthermore, it may lead to contamination of seafood for human consumption.
“What are the chances of contaminating food supplies?” Dr. Drazen questioned. He expressed a desire for answers regarding this issue before mining commences, as the information is currently lacking.
What do mining companies assert?
The mining industry claims to be adopting a sustainable and environmentally responsible approach to deep-sea mining through research and collaboration with the scientific community.
Their research includes fundamental studies in seabed geology, biology, and chemistry, documenting thousands of species and providing valuable imagery and footage from the deep sea. Dr. Drazen noted that interest in undersea mining could promote research efforts that might otherwise be hard to fund.
Initial tests of recovery equipment have revealed some insights into the anticipated effects related to sediment plumes, yet modeling is limited in forecasting outcomes at a commercial scale.
Impossible Metals, a California-based underwater mining firm, utilizes artificial intelligence to create a transport container-sized underwater robot designed to harvest large, free-living nodules. In 2022, the Metals Company, a Canadian deep-sea mining entity, extracted approximately 3,000 tons of nodules from the ocean floor and gathered data regarding the sediment plume generated during the process.
In March, the Metals Company indicated plans to bypass international regulatory bodies associated with the United Nations overseeing submarine mining, instead seeking authorization through NOAA.
During an interview on Thursday, CEO Gerald Baron stated that the executive order “does not serve as a shortcut” for previous environmental assessments, emphasizing that the company has “conducted over a decade of environmental research.”
White House spokesperson Anna Kelly affirmed that the United States would adhere to two domestic laws governing deep-sea exploration and commercial endeavors within U.S. waters. “Both laws mandate extensive environmental impact assessments and compliance with stringent environmental standards,” she noted.
What are the long-term risks?
Many scientists harbor skepticism regarding the well-understood environmental consequences of underwater mining, as viable predictions about long-term results remain elusive.
Disturbing the base of the food chain can have cascading effects on the entire marine ecosystem. For instance, if sediments dilute the food supply for plankton, they could face starvation due to an inability to extract sufficient organic matter from the clouds of sea dust.
Small plankton serve as a fundamental food source, whether directly or indirectly, for nearly every marine organism, including whales.
Understanding potential impacts poses challenges due to the slow life processes at the seabed. Deep-sea fish can live for hundreds of years, while corals can endure for millennia.
“The timeline of life here is significantly different,” Dr. Levin explained. “It raises numerous uncertainties regarding responses to environmental disturbances.” Conducting 500-year experiments to ascertain whether these ecosystems can recover or adapt is a daunting task for humans.
Additionally, there’s no assurance that damaged habitats will be restored or that harm to the seabed will be mitigated. Unlike terrestrial mining, “a strategy for deep-sea mining is absent,” Dr. Oucht remarked. “There is currently no scientific evidence supporting the restoration of ecosystems post-damage.”
Some experts have raised concerns about the necessity of undersea mining, arguing that land-based mining could meet the growing metal demands.
Proponents of deep-sea mining assert that the environmental or carbon footprint is less significant compared to traditional mining practices for those same minerals.
“To date, there has been no actual recovery of minerals,” stated Amy Gartman, a marine researcher leading the U.S. Geological Survey’s Undersea Minerals Team, referring to commercial-scale mining. “We are comparing theoretical scenarios with actual land mining methods. Once someone initiates extraction in any of these ventures, we will gain a clearer understanding.”
At least three medical journals have received correspondence from the U.S. Department of Justice, raising questions about their editing practices and urging them to maintain their independence.
The Lancet, a prominent British medical journal that did not receive one of these letters, published an editorial condemning the inquiries as “harassment” and threats, stating that American science has been “harshly detached” under the Trump administration.
Recently, Interim U.S. Attorney Ed Martin for the District of Columbia contacted the Chest Journal, which focuses on chest medicine, suggesting it has a partisan bias. The letter included inquiries about measures needed to combat misinformation, incorporating various perspectives.
This communication sparked outrage from the First Amendment group and several scientists, who expressed concerns that such law enforcement actions could undermine academic freedom and free speech. The letter encouraged the journal to clarify that its publisher, the American College of Chest Physicians, “supports the journal’s editorial independence.”
This week, the New England Journal of Medicine confirmed to NBC News that it had also received a similar letter from an interim U.S. attorney.
In a response shared with NBC News, the journal’s editor-in-chief, Dr. Eric Rubin, defended its rights as an independent publisher, emphasizing their strict peer review and editing process to ensure the objectivity and reliability of the research published. “We uphold their First Amendment rights to editorial independence and free expression in medical journals,” Rubin stated. “The journal remains committed to fostering academic scientific dialogue and supporting authors, readers, and patients.”
The third journal, Obstetrics and Gynecology, also confirmed receiving a letter from Martin.
“Obstetrics and Gynecology editorially operates independently from ACOG, although we share the mission of improving outcomes for individuals needing obstetric and gynecological care,” a representative from the American University of Obstetrics and Gynecology remarked in an emailed statement. “We take pride in our journal’s focus on scientific data and patient-centered, respectful, evidence-based care.”
The DC office of the Department of Justice did not respond to NBC News’ request for comment.
Meanwhile, The Lancet, which has been publishing for over 200 years, adopted a more assertive tone. In a scathing editorial in solidarity with other journals, it described the letter from the Justice Department as “harassment” within the broader context of the Trump administration’s “systematic dismantling of U.S. scientific infrastructure.”
“This is a blatant attempt to intimidate journals and infringe upon their rights to independent editorial oversight. The Lancet and other medical journals are being targeted by the Trump administration,” the editor remarked. “Medical journals should not expect to be spared from the administration’s attacks on science, as institutions like the NIH, CDC, and academic medical centers are also being affected.”
Scientific journals are essential for disseminating new discoveries and insights among colleagues. Some journals are managed by specialized experts, while others are published by organizations with a focus on science. A reputable journal ensures that research undergoes thorough peer review, where external experts appraise it for errors and research quality.
The scrutiny of scientific journals occurs as the Trump administration has faced reductions in funding and staffing.
NBC News inquired with several major scientific and medical journal groups regarding whether they received similar letters from the Department of Justice.
Representatives from Science, Elsevier, Nature, and JAMA, the medical journal of the American Medical Association, did not reply to requests for comment.
Wiley Publishing Company acknowledged receipt of the letter from an interim U.S. attorney but did not provide further details.
“We remain committed to the highest standards of editorial independence, academic rigor, and publication ethics,” a Wiley spokesperson stated. “Our journal evaluates submissions based on their scientific merits and collaborates closely with social partners to ensure a wider perspective contributes to the advancement of knowledge.”
Dr. Paul Uribe, a former military pathologist who consulted nationwide and assisted in solving a series of insulin-related murders at a veteran hospital in West Virginia, noted to NBC News that there are insufficient protocols to guide pathologists and emergency room doctors in effectively managing such cases.
“You’re not going to accidentally stumble upon an insulin murder,” Uribe remarked. “You must have a suspect and actively search for it; if you’re not investigating, you won’t discover it.”
For more information on the West Virginia case, tune in to “Devil’s in the Detailing” on “Dateline” tonight at 9 ET/8 CT on April 25th.
While these crimes are uncommon, Uribe highlighted an alarming increase in related incidents across the U.S. In Pennsylvania, several nurses confessed to attempting to murder 19 patients using insulin across five facilities between 2020 and 2023, resulting in 17 fatalities. Additionally, at the West Virginia Veterans Hospital, nurses confessed to killing seven patients with insulin in 2021.
Uribe pointed out that no state has officially established protocols for emergency room physicians and medical inspectors regarding insulin-related cases, noting that only West Virginia has attempted to address this significant oversight. Legislation introduced this year aims to obligate emergency rooms to test for insulin in patients exhibiting symptoms of insulin poisoning.
Jonathan Jones, former president of the American Academy of Emergency Medicine, expressed concerns regarding insulin overdoses but asserted that health care should not be legislated.
“The best medical care is delivered by well-educated, trained, and board-certified physicians, not legislators,” he stated in an email to NBC News. “We are committed to continuous medical education regarding this issue and support the standards for specialist physicians, but we oppose mandatory treatment directives.”
He declined to comment on whether emergency rooms should adopt stricter guidelines.
When asked if forensic pathologists need improved protocols, Reade Quinton, president of the National Association of Medical Examiners, replied, “I’m not sure that’s the right question. What medical examiners require is access to field information, witness statements, and medical records without obstruction.”

The chief sponsor of the West Virginia bill did not respond to requests for comment. Nevertheless, the parents of Michael Cochran, after whom the bill is named, believe this legislation could serve as a model for the nation and help others avoid the painful search for answers they endured for years.
“They shouldn’t have to wait for answers as we did,” remarked Cochran’s mother, Donna Bolt, to Dateline. “Six years.”
Seven deceased patients at VA Hospital
Uribe’s investigation into insulin-related murders began at the Veterans Hospital in Clarksburg, West Virginia, where he was tasked with examining a series of mysterious deaths among elderly patients in late 2018.
These occurrences can result from excessive insulin doses, which regulate blood glucose levels in diabetic patients.
Some veterans were diabetic, Uribe recalled, while others were not. He was requested to uncover a definitive piece of evidence that could confirm insulin as the murder weapon.
For emergency room doctors and pathologists, he noted, identifying such cases is complicated due to insulin’s rapid metabolism. The “C-peptide” test referenced in West Virginia law can detect insulin, but timing is crucial. It must be conducted before any treatment interventions for hypoglycemia are started.
“If glucose is administered, it triggers the body’s natural insulin release, negating the C-peptide measurement,” he explained.
Furthermore, many small hospitals lack access to these specific tests.
Uribe described two primary methods for pathologists to detect insulin. One prevalent method involves injection, which may leave temporary traces in body tissues at the injection site. Insulin can also be found in postmortem vitreous fluid from the eye, he noted.
In West Virginia, testing of tissue samples from seven veterans’ remains revealed trace amounts of insulin in some victims, including those without diabetes or any prior prescriptions for the drug.
“This provided conclusive evidence that they had been injected with insulin,” he stated.

Nursing assistant Letta Mays was later identified as the prime suspect in this case. She confessed to administering a lethal dose of insulin, pleaded guilty to seven counts of second-degree murder and one count of assault with intent to murder concerning the death of an eighth man. Mays was sentenced to seven life terms.
Deadly dose from a pharmacist
In Uribe’s subsequent case, pharmacist Natalie Cochran was convicted in January for giving her husband a lethal dose of drugs amid a conspiracy to cover up millions in fraudulent activities involving friends and relatives.
Resolving this case took several years.
In February 2019, Michael Cochran was found unresponsive and later transitioned from a ventilator to hospice care at the age of 38. His death certificate classified his cause of death as “natural.”
Michael and Natalie Cochran.Dateline
Michael Cochran’s hospital records indicated that upon admission, his blood sugar levels were dangerously low, despite his lack of any diabetes history, Uribe informed. Unfortunately, insulin testing was not conducted at that time.
Still, West Virginia State Police detective Tim Bledsoe suspected Natalie Cochran’s involvement in her husband’s demise. During a search of her home, a partially used vial of insulin was discovered in the refrigerator.
When Bledsoe questioned Natalie about the vial, she claimed it was meant for her neighbor’s diabetic son. However, the neighbor, Jennifer Davis, contradicted this, stating that Natalie had asked for insulin for herself to aid recovery from a fake cancer diagnosis that prosecutors argued she later fabricated.
Davis recalled that Natalie requested insulin the same morning Michael first became ill.
Two years after Michael Cochran’s death, his wife was charged with murder. An autopsy commenced seven months after his passing, but by then, his body was significantly decomposed, leading medical inspectors to classify the cause of death as undetermined, according to Bledsoe.
The timeline regarding the autopsy’s delay and whether insulin testing was conducted post-mortem remains unclear. The West Virginia Department of Health and the Office of Personnel, which oversees medical examinations, did not respond to inquiries.
Uribe expressed skepticism that any post-mortem evidence of insulin could have been retrieved given the elapsed time between Michael’s drug administration and his death.
The inconclusive findings, combined with the absence of concrete evidence, led the Raleigh County District Attorney to lower the charges, according to Tom Truman, the current prosecutor.
“If you lack a medical examiner advocating murder, that’s a significant concern,” he remarked to Dateline.
Re-examination yields clarity
However, two years later, the fees were re-evaluated after Uribe was invited to investigate further. During the new autopsy and examination, Uribe searched for potential injection marks, but by this time, Michael’s body had severely deteriorated, preventing any tests from being taken.
Nonetheless, Uribe noted that potential explanations for Michael Cochran’s hypoglycemia, such as infections and severe sepsis, were not documented in his medical records. Considering the circumstances surrounding his death, Uribe classified it as an insulin murder.
During the trial, the endocrinologist who testified for the prosecution conceded that there was no clear explanation for Michael Cochran’s low blood sugar levels.
Michael and Natalie Cochran.Dateline
Natalie Cochran’s defense attorneys acknowledged her involvement in fraudulent activities with various associates, whereby she also pleaded guilty to a separate federal fraud and money laundering case; however, they insisted that she was innocent of her husband’s death.
On January 29th, following two hours of deliberation, the jury found Natalie Cochran guilty of first-degree murder. She received a life sentence without the possibility of parole.
For Uribe, this case, alongside others at the Veterans Hospital, underscores an urgent need for improved insulin overdose protocols.
Such protocols could assist physicians in recognizing red flags like unexplained hypokalemia, which arises from critically low blood sugar levels in non-diabetic patients or from fatal excessive insulin use.
Additionally, he emphasized the need for C-peptide testing to be done prior to any treatment.
Pathologists should look for potential injection sites and conduct vitreous humor tests, he advised.
“If insulin can be detected in the vitreous fluid of someone with no history of diabetes or prior prescriptions, it could substantiate a case,” he concluded.

David Patong, an innovative and ideal ophthalmologist, initiated Project Orvis, where he transformed United Airlines jets into flying hospitals, transported surgeons to developing nations, trained local doctors, and passed away on April 3 at his residence in Reno, Nevada.
His son Townlee confirmed his demise.
Dr. Patong (pronounced Pay-Ton), the son of a renowned New York ophthalmologist and descendant of Iranian Shah and financier J. Pierpont Morgan, taught at the Wilmer Eye Institute at Johns Hopkins University in the early 1970s. He was disheartened by the rising number of preventable blindness cases in remote regions.
In his memoir “Second Sight: A View from The Anay Doctor’s Odyssey” (2011), he wrote, “We needed more ophthalmologists… but also needed to enhance medical education for existing physicians.”
Considering various options like shipping equipment trunks and using medical ships similar to Project Hope, he ultimately founded Project Orvis in 1973 with the support of wealthy individuals like Texas oilmen Leonard F. McCollum and Betsy Trippe Wainwright.
After the moon landing in 1969, Dr. Patong believed that the concept of Moonshot was feasible. He envisioned converting large aircraft into operating rooms, educational classrooms, or any required facility.
He relentlessly sought ways to obtain an airplane, approaching the military and universities without success. Dr. Patong, described by Bruce Spivey as charming and unrelenting, eventually raised the necessary funds himself.
In 1980, with the help of Betsy Trippe, he secured a donated DC-8 Jet from United Airlines to create a flying hospital. This marked the beginning of life-changing missions to various countries where local health workers witnessed surgeries in specially-equipped classrooms onboard.
The Flying Eye Hospital facilitated surgeries in multiple nations like Peru, Jordan, and Nepal, receiving visits from prominent figures like Mother Teresa and Fidel Castro. Their impactful work caught the attention of media outlets like the Sunday Times, sharing stories of patients like Julia.
Julia’s transformative surgery showcased the effectiveness of their efforts in restoring vision to the visually impaired. Despite challenges, the procedure led to profound moments of discovery for Julia as she regained her sight gradually.
Born on August 16, 1930, in Baltimore, David Paton hailed from a family with a rich medical background. His upbringing in Manhattan and exposure to eminent personalities shaped his journey towards medical innovation.
His formative years were filled with experiences among intellectuals and socialites, leading to his academic pursuits at Hill School and Princeton University. He maintained close ties with lifelong friend James A. Baker III while excelling in his medical career.
In addition to his contributions to Project Orvis, Dr. Paton served as a distinguished medical director in institutions like King Khaled Eye Specialist Hospital. His dedication to providing eye care to royalty in Saudi Arabia reflected his commitment to improving global healthcare.
Although his formal ties with Project Orvis ended in 1987, Dr. Patong continued to offer guidance informally. The organization, now known as Orbis International, has expanded its operations with a fleet of planes and a robust track record of surgeries and training sessions.
Orbis International’s enduring impact is a testament to Dr. Patong’s visionary approach to healthcare. The organization’s innovative use of airplanes as a platform for medical missions has revolutionized the way eye care is delivered globally.
During the warm Antarctic season, a refined Norwegian passenger ship is known as Ms Fridtjof NansenDeparting regularly from Argentina, head south along the turbulent drake passageway to the Antarctic Peninsula. The cruise is home to more and more wealthy adventurers, bucket listers, and increasingly polar scientists seeking to collect data as public funds for research in Antarctica under the Trump administration.
The National Science Foundation is one of the world’s largest funders of scientific research and has an annual budget. Approximately $9 billion This supports most of the research in the United States Antarctic. Over the past few months, the Trump administration has ordered agencies to cut deeper, making scientists wonder how they will study everything, from melting glaciers and ice sheets to the effects of pollution from power plants and wildfires.
On Thursday, National Science Foundation director Seturaman Panchanashan resigned after the White House directed him to cut the agency’s budget and staff by more than half. According to an exclusive report from Science.
Panchanathan’s resignation follows Elon Musk’s previous orders from government efficiency Freeze fund All new research grants from the National Science Foundation, and the announcement that Doge will be over last week Over $200 million “Wild” research grants given by the agency.
Some experts are concerned that the Trump administration continues its National Science Foundation It may inform you of the end For research into the United States of Antarctica.

James Burns, co-founder of the Antarctic and Southern Ocean Coalition, is an international alliance for environmental and non-governmental organizations focusing on Antarctic conservation and research, and says the National Science Foundation has become “wicked language” within much of the Trump administration. “For whatever reason, there’s so much to learn in Antarctica, that’s not good on many levels for us.”
Antarctica-based research projects have already declined for several years – disrupted decades of robust fieldwork; Never recovered from Covid-19 restrictions. Currently, research on the world’s southernmost continent has been facing several years under Trump’s slash and burning policies.
However, I’m riding on Fridjov Nansen.And its sister ship, Ms. Roald Amundsen, Polar Scientist, has reliable funds for their research. HX Expeditions, which operates two Antarctic ships, hosts researchers from institutions such as West Washington University. University of California, Santa Cruz. National Snow and Ice Data Center. Their rooms and boards are covered by the purchase of tickets from tourists sailing to Antarctica for a once-in-a-lifetime trip.
“If we can’t pay customers to allow our ship to go south, we can’t support the research we are helping out,” said Verena Meraldi, chief scientist on the HX Expedition. “It’s not easy [to get there]. There are not many flights coming down here, and fewer research vessels. ”

Tourists traveling on the HX expedition are part of the explosive ecotourism industry, focusing on experiencing nature while helping to preserve the local area. The number of visitors to Antarctica has increased from about 8,000 each year in the 1990s to over 120,000 per year. International Antarctic Tour Operators Association. By 2035, the ecotourism market will be like that projection It will grow to over $550 billion. Ms Fridtjof Nansen on a late March expedition to the Antarctic PeninsulaIt was home to over 400 ecotourists and several researchers, including Freia Aardred, a doctoral student at Durham University in the UK.
Alldred moved along with sterilized bags to collect samples of seaweed grown in Antarctica waters and snow algae. She has studied how climate change affects the carbon content of these Antarctic species, and Cruises has provided a unique opportunity to collect new samples.
“We’ve never been anywhere with a research foundation,” says Alldred. “Instead, if I went to a base in the Antarctic in England, I could only sample within my area. Here I have gone to five different sites throughout the peninsula that may not have been previously studied.”
The boat was housed nearby scientists and ecotourists, giving scientists the unusual opportunity to explain their work directly to non-scientists through interactive sessions in an onboard lab. For ten days, enthusiastic passengers attended lectures from resident researchers, ate with them at the ship’s restaurant, sharing their first steps in the vast polar deserts of Antarctica.
“It’s incredible to share these experiences with people, explain why we do research, what kind of questions we answer, and they see them firsthand,” said Chloe Lou, a researcher who works with the California Ocean Alliance to capture the impact of tourist boats on Antarctica whales. “It fires me for my passion for my work.”
Federal prosecutors in Washington reached out to the New England Journal of Medicine with unsubstantiated inquiries that implied the journal, considered one of the most prestigious in the world, may be biased towards certain viewpoints and influenced by external pressures.
NEJM editor Dr. Eric Rubin described the letter as “blatantly threatening” in an interview with the New York Times.
Republican activist Edward Martin Jr., serving as interim U.S. attorney in Washington, sent similar letters to at least three journals. Martin has faced criticism for using his position to target opponents of the administration.
The letter accused the journal of taking sides in scientific debates and posed accusatory questions about bias and the selection of research articles.
Will they consider submissions from scientists with differing perspectives? How will they handle authors whose work they have published that may have misled readers? Are they transparent about the influence of supporters, funders, advertisers, etc.?
Martin also raised questions about the role of the National Institutes of Health, which funds some of the research published by the journal, and its involvement in the development of submitted articles.
Amanda Shanor, a First Amendment expert at the University of Pennsylvania, emphasized that information published in reputable medical journals like NEJM is widely protected by the Constitution.
She explained that journals have the same rights as newspapers in most cases, with the Constitution providing the strongest legal protection.
“There is no legal basis to suggest that medical journals are not afforded the strictest First Amendment protections,” she stated. “It seems to be an attempt to instill a sense of fear and censorship that impacts people’s freedom of expression. This raises constitutional concerns.”
It is unclear how many journals received these letters or the criteria Martin used to target publications. The U.S. Attorney’s Office in Washington did not respond to requests for comment.
“Our role is to assess and evaluate science in an impartial manner,” Dr. Rubin stated. The questions raised seem to insinuate biases in our operations – it is quite vagueThis introduces a threatening element. ”
Former editor of Science magazine, Jeremy Berg, believed the letter was an attempt to coerce journals into publishing papers aligning with the administration’s views on climate change and vaccines, even if the research quality is lacking.
National Health Secretary Robert F. Kennedy Jr. mentioned in an interview with the “Dr. Hyman Show” podcast last year that NEJM was involved in disseminating misinformation and distorting scientific facts.
Department of Health and Human Services spokesman Andrew Nixon declined to comment on Kennedy’s involvement in the letter.
Kennedy expressed his intention to possibly take legal action against medical journals under the Federal Anti-Corruption Act.
“I plan to file a lawsuit against you under general tort laws and the Assault Act,” he stated. “Unless you have a plan to demonstrate how you will begin publishing genuine scientific work, I will find a way to pursue legal action against you.”
Dr. Jay Bhattacharya, the new head of NIH, has criticized mainstream science journals and recently co-founded a new journal that offers alternative perspectives on Covid.
The UK-based Lancet showed support by editing Editor Skas’s response, calling it “an obvious attempt to intimidate and stifle editorial independence.”
“American science and medicine are being closely watched worldwide,” the editor stated.
One of Martin’s letters was directed at the journal Chest, a publication focused on technical research in areas like lung cancer and pneumonia. It was reported by The New York Times that at least two other publishers received similar letters.
These publishers chose not to speak publicly for fear of repercussions from the Trump administration.
Dr. Rubin also expressed concerns about potential political backlash. Science journals often rely on public funding indirectly, with universities using federal grants to pay for subscriptions.
“Are we concerned? Absolutely,” he said. “But we are committed to doing what is right.”
Martin gave the magazines until May 2nd to respond to his inquiries. NEJM has already issued a statement refuting the accusations made against their journal.
“We maintain strict peer review and editing processes to ensure the integrity and trustworthiness of published research,” the statement affirmed. “We uphold the editorial independence of medical journals and their inherent right to protect their freedom of expression.”
This is not NEJM’s first run-in with the Trump administration.
In 2020, the Journal dismissed an editor who criticized the president’s pandemic response. This marked the first time in its 208-year history that the Journal took a stance on a political figure.
Dr. Rubin speculated that Martin’s letter may be related to this editorial decision. While the Journal Chest did not publish on Trump’s first term, the connection was noted.
On March 11, approximately 50 judges gathered in Washington for a six-month meeting of the Judicial Council, which oversees the administration of federal courts. This meeting marked the first gathering since President Trump assumed office.
Discussions during the meeting focused on staffing levels, long-term planning, and the increasing threats to judges and their safety, according to attendees.
At one session, Judge Richard J. Sullivan, chairman of the conference’s Judicial Security Committee, raised concerns about potential threats to the safety of judges. He highlighted the authority that the US Marshals Service, overseen by the Justice Department, has in judicial security matters. Given the history of former officials like Mike Pompeo and John Bolton having their security stripped by Trump, Judge Sullivan wondered if federal judges could be the next target.
Judge Sullivan, who was appointed by President George W. Bush and later elevated to appeals judge by Trump, emphasized the importance of trusting the head of judicial security amidst uncertainties about potential threats to the federal bench.
While there is no evidence that Trump is considering revoking judges’ security, Judge Sullivan’s remarks highlighted the unease among judges about the agency responsible for their safety ultimately answering to the President through the Attorney General, without sufficient funding to address rising threats.
In a statement, the Marshall Services affirmed their commitment to following all legal orders from federal courts to ensure the protection of judges, jurors, and witnesses. However, concerns have been raised about the frozen court security funds at a time when threats to federal judges are on the rise.
Judge Robert J. Conrad Jr., in a letter to Congress, expressed disappointment that court security funds remain stagnant despite the escalating threats. The total amount spent has seen minimal increase, despite inflation and higher staff salaries.
The former US S’s responsibilities have expanded to include protecting the Supreme Court’s residence in response to growing threats. Concerns about the oversight of Marshall Services have led some to propose transferring control of the agency to the judiciary for better protection of judges.
As the threats to judges continue to increase, some members of Congress are considering legislation to make judicial security more independent. The former US S’s response to court orders and the potential interference from political branches remain critical issues to address for the safety of judges.
Despite the challenges, efforts to reduce Marshall Services to increase efficiency may impact the agency’s ability to fulfill its crucial mission of protecting judges and upholding court orders.
Late yesterday, Seturaman Panchanathan, whom President Trump hired to run the National Science Foundation five years ago, left. He didn’t say why, but it was clear enough. Last weekend, Trump cut more than 400 active research awards from the NSF, and he is pressing Congress to halve Congress’ $9 billion budget.
The Trump administration has targeted American scientific companies, an engine of research and innovation that has been inducted for decades. The National Institutes of Health, the National Science Foundation, the Centers for Disease Control and Prevention, and NASA are cutting or frozen budgets. Thousands of researchers have been fired or paid back.
The confusion is confusing. Isn’t science an eternal power? Does it contain disease? Would it help you compete with China? Why not attract the kind of immigrants the president says he wants? In this edition of the newsletter, you will break the huge thing to understand the fuss.
investment
American research thrives under a sponsorship system that highlights dollars that Congress has approved to universities, national labs and labs. The Knowledge Factory employs tens of thousands of researchers, bringing talent from around the world, creating scientific breakthroughs and Nobel Prizes.
Science moves slowly, so it’s a slow moving system. Discoveries are often indirect and repetitive, and include collaboration between researchers who require years of granted education to become experts. Startups and businesses that need quick returns on investments are usually unable to wait long for long money or risk.
Science is capital. With some measures, all dollars spent on research will return at least $5 to the economy.
President Trump is not patient. He reimbursed university research into AIDS, pediatric cancer and solar physics. (Two well-known researchers compiled the list Lost NIH grants and NSF Awards. ) The administration has also fired thousands of federal scientists, including meteorologists from the National Weather Service. CDC’s pandemic preparation expert. A black researcher at the National Institute of Occupational Safety and Health. Already built for $3.5 billion over a decade, the next generation space observatory is waiting for a launch that could never happen now.
Alienate scientists
Administrative authorities provide various reasons for the crackdown: cost reduction, government efficiency, and “protecting women from gender ideological extremism.” Many grants have been eliminated because they include terms such as climate, diversity, disability, trans, or women. Some portrayed the administration’s rage, as the application included a DEI statement requested by the previous administration.
You don’t need a telescope to see where this leads. American leaders have historically seen science as an investment in the future. Will this administration seize it? One third of American Nobel Prize winners were foreign-born, but immigration crackdowns wiped out scientists like Xenia Petrova, a Russian who ages at Harvard University and is now sitting in a detention center in Louisiana. Australian scholars have stopped attending conferences in the US for fear of being detained, The Guardian reported.
Now, some American scientists are looking for an exit. France, Canada and other countries are courting our researchers. A recent poll by Nature magazine found that more than 1,200 American scientists were considering working abroad. Journal recruitment platforms were seen 32% of overseas positions more applications Between January and March 2025, this was higher than the same period last year.
Paleontologists describe the oldest known members of Haidomyrmecinae – An extinct subfamily of ants that were only during the Cretaceous period – preserved as an impression of limestone rocks in the Krato Formation in northeastern Brazil.
Vulcanidris cratensisholotype. Scale bar – 2 mm. Image credit: Lepeco et al. , doi: 10.1016/j.cub.2025.03.023.
It has been named Vulcanidris cratensisthe new ant species lived 113 million years ago (early Cretaceous period).
This species represents the oldest and most definitive ant known in science, and is also the most complete evidence of the early evolution of ants in the fossil record.
“Vulcanidris cratensis The author, Dr. Anson Lepeco, a paleontologist at Dr. Zloria da Universad de Sao Paulo, stated:
“What makes this discovery particularly interesting is its belong to an extinct “hell ant”, known for its strange predatory adaptation. ”
“Even though it is part of an ancient lineage, the species already exhibits highly specialized anatomical features, suggesting unique hunting behaviors.”
The oldest previous ants were found in France and Myanmar and were preserved in amber instead of limestone.
The presence of hell ants in Brazil indicates that ants are already widely distributed and diversified early in their evolution.
“There was an hell ants explained by Amber, and this was the first time I could visualize them in a rock fossil,” Dr. Lepeco said.
Dr. Lepeco and his colleagues discovered a very well-preserved Ant specimen and systematically examined one of the world’s largest collections of fossil insects from. Krato Layera deposit known for its exceptional fossil preservation.
“When we encountered this extraordinary specimen, we quickly recognized its importance not only as a new species, but also as a potentially conclusive evidence of ants in the Krato Formation,” Dr. Lepeco said.
“The finding highlights the importance of a thorough investigation of existing collections either privately or in museums, and highlights the fauna of Brazilian paleontology and the country’s unexposed fossil insects.”
Using microcomputed tomography imaging, paleontologists discovered it Vulcanidris cratensis It was previously closely related to hell ants, known only from specimens preserved in Burma mber, Myanmar.
This finding shows that ants must have been widely distributed worldwide and repeatedly crossed Cretaceous lands.
But what surprised them most was the professional traits of Hell’s Ants.
“We were hoping to find the features of the hellish ant, but we were shocked by the features of the feeding device,” Dr. Lepeco said.
“Unlike modern ants with laterally moving mandibles, this species had a mandible with face and face projections running forward in front of their head and eyes.”
“Finding such anatomically specialized ants for 113 million years ago challenges our assumptions about how quickly and complex adaptations these insects have developed.”
“The complex forms suggest that even these early ants had evolved sophisticated plundering strategies that were already very different from their modern counterparts.”
“The discovery of this new ant specimen raises broader questions about the evolutionary pressures that have led to the unique adaptation of hell’s ants.”
“Advanced imaging tools allow us to explore these fossil specimens in greater detail than ever before.”
Discovery of Vulcanidris cratensis Reported in a paper It’s published in the journal today Current Biology.

High-energy photons produced deep within gamma-ray burst jets emerge from decayed stars can dissolve the outer stellar layer into free neutrons, causing a series of physical processes that lead to the formation of heavy elements. paper It is published on Astrophysical Journal.
The high-energy photonic jet (white and blue) passes through a collapse with a black hole at its center. The red space around the jet represents a coco where free neutrons can be captured and caused the R process. Image credit: Los Alamos National Laboratory.
The formation of the heaviest elements relies on astrophysical environments with large amounts of neutrons.
Neutrons are found in the medium under extreme pressure, either bound to the nucleus.
Free neutrons are rare because they have a half-life of less than 15 minutes.
“The creation of heavy elements such as uranium and plutonium requires extreme conditions,” says Dr. Matthew Mumpoir, a physicist at the Los Alamos National Laboratory.
“There are several viable yet rare scenarios in the universe where these elements can form, and all such locations require a large number of neutrons. We propose a new phenomenon where these neutrons are not present and dynamically generated by stars.”
The key to generating the heaviest elements in the periodic table is known as the rapid neutron capture process or R process, and is believed to be responsible for the production of all thorium, uranium and plutonium that occur naturally in the universe.
The team’s framework takes on the challenging physics of the R process and solves them by proposing reactions and processes around the collapse of the stars.
In addition to understanding the formation of heavy elements, the proposed framework will help address key issues regarding neutron transport, multi-objective simulations, and observation of rare events. All of these are interesting for national security applications, which can gather insights from research.
In the scenario proposed by researchers, when nuclear fuel is exhausted, a large star begins to die.
It is no longer able to push its own gravity up, and a black hole forms in the center of the star.
If the black hole is spinning fast enough, the framedrazing effect from the very powerful gravity near the black hole will wind up the magnetic field and fire a powerful jet.
Subsequent reactions create a wide range of photons, some of which are high-energy.
“The jet blows stars before it, creating a hot coco of material around the jet, like a freight train plowing through the snow,” said Dr. Mumpower.
At the interface of jets with star materials, high-energy photons (i.e. light) can interact with the nucleus and convert protons into neutrons.
Existing nuclei can also be dissolved in individual nuclei, creating more free neutrons to power the R process.
Team calculations suggest that interactions with light can create neutrons very quickly in nanosecond order.
For charging, a strong magnetic field traps the protons in the jet.
The merciless neutrons are ploughed from the jet to the coco.
After experiencing relativistic shock, neutrons are very dense compared to the surrounding star material, which can lead to the R process, forging heavy elements and isotopes, and banished into space when the stars are torn apart.
The process of protons converted into neutrons and the free neutrons that escape to the surrounding coco to form heavy elements, encompasses all four basic forces of nature, accompanied by a wide range of physics principles. It combines the real multiword problems, the fields of nuclear and nuclear physics, with fluid mechanics and general relationships.
Despite the team’s efforts, more challenges remain as the heavy isotopes created during the R process have never been done on Earth.
Researchers know little about their properties, including atomic weights, half-life, and more.
The high energy jet framework proposed by the team may help explain the origin of kilonovas (the glow of optical and infrared electromagnetic radiation) associated with long gamma-ray bursts.
“Star melting via high-energy photon jets provides an alternative origin for gravity and the production of kilonova that can be produced. This may not have previously been thought to be related to star collapse,” the scientist said.

Every day, over a billion cups of coffee are consumed, including French presses, espresso, and cold brewing.
Physicist Arnold Mattissen from the University of Pennsylvania has a bias towards the art of pouring coffee. He manually pours hot water over ground beans, filters it into a pot or mug, and believes that applying fluid dynamics principles could improve the process even further.
Dr. Mathijssen, along with two like-minded students, conducted research on optimizing the pouring method. Their scientifically-backed advice is to pour water in high, slow, and steady streams to maximize extraction and enhance the flavor of the coffee without any additional costs.
Results from a recent survey published in the Journal Physics of Fluids show how the coffee pouring process in the kitchen can lead to new scientific directions in different culinary techniques. This demonstrates how science can improve the art of cooking.
Dr. Mathijssen, who primarily studies biological flow physics, began experimenting with food during the Covid-19 shutdown when he lost access to his lab. This led to exploring the physics involved in various cooking techniques, including pasta stickiness and whipped cream structures. His interest in kitchen physics remains high.
While Dr. Mathijssen has returned to the lab, his passion for kitchen physics continues. The coffee research was inspired by scientists in his group who kept detailed notes on daily coffee brewing experiments in the lab, noting details such as bean origin, extraction time, and flavor profiles.
Graduate student Ernest Park designed a formal experiment using silica gel beads in glass cones to simulate pouring water into coffee grounds from different heights, capturing the dynamics with a high-speed camera.
And there is the evolutionary rarity of carnivorous caterpillars. And now, scientists have discovered not only a food for other insects, but also a very hungry caterpillar.
Called The Bone Collector, this scary taste in Caterpillar and Couture was explained in the Journal on Thursday Science. “The behavior was completely unknown,” said Daniel Rubinoff, an entomologist and research author at the University of Hawaii at Manoa. His team initially compared caterpillars to raw crime scenes.
Bone collector’s caterpillar is found only within the six-square miles of a single mountain range on Oahu. So it only exists in co-necks spun by spiders in logs and rock caves. When caterpillars almost slip about the web, they clean dead insects and other arthropods that have been soaked in sticky silk.
According to David Wagner, an entomologist at the University of Connecticut, Caterpillar’s reliance on Spiders presents one of nature’s most unlikely connections, as he was not involved in new research. “It’s amazing how caterpillars tie their fate to spiders. It’s clear and current danger for both caterpillars and moth,” Dr. Wagner said. He only knows one other species that frequently visits spider nets. But the species are vegetarians who snack on plant ingredients caught in the web.
Dr. Rubinoff first encountered the bone collector’s caterpillar in 2008 while examining the inner web of a hollow tree. Caterpillars are extremely rare. Over 150 field studies in the area produced only 62 bone collector specimens.
Scientists determined that bone collectors belong to hyposporoma, a diverse genus of small moth species found only in Hawaii. The larva stage rotates silk protective cases that resemble everything from Kandi wrappers to cigars.
Like hermit crabs, these caterpillars carry their cases before moving before appearing as fully grown moth. Some species decorate mobile homes with wood, algae and shells to blend into the environment.
Bone collector Caterpillar gives an eerie spin on his practice. Using silk, caterpillars weave small pieces of dead insects they encounter on the spider web. Researchers have identified parts from six families of insects attached to caterpillars, including the heads of weevils and the abdomen of beetles. Caterpillar also incorporates fragments of the exoskeleton molted by Arachnid’s neighbors.
Dr. Rubinoff and his colleagues brought some bone collectors back to the lab. They were surprised at how loud the caterpillars were when they were to decorate their lawsuit. “These caterpillars can identify differences in the objects of their environment,” Dr. Rubinov said. The larvae chose to avoid other available debris and harvest only from insect corpses.
But the ruins are not. Caterpillar uses the lower jaw to carefully rotate and investigate future body parts. Something too large will bite you in a more comfortable size.
The caterpillars gathering bones are too noisy about their diet. The team discovered that caterpillars, including one another, eat insect prey that can catch.
But they have to fight against an eight-legged landowner. The team observed bone collector caterpillars that frequently and frequently visit the web of at least four introduced spider species. The team assumes that Caterpillar’s horrifying outfits will help disguise them among insects trapped in the web. Dr. Wagner suspects caterpillars will undermine the appeal of their culinary culinary by disguising them as “a pile of garbage” of objects that the spiders didn’t scarf down.
The bone collector approach appears to be working. Researchers never observed spiders consuming bone collectors or engulfing them in silk.
The team studied bone collector genetics and determined that it was likely that it diverged from other carnivorous hypofluvium caterpillars more than 5 million years ago. This may be millions of years before Oahu emerged from beneath the sea, and the ancestors of bone collectors once lived on other islands.
Bone collector’s current paradise slices may be at risk. Caterpillars have adapted to thrive in nets spun by non-native spider species, but their habitat is threatened by invasive ants and parasitic wasps. According to Dr. Rubinoff, conservation attention is desperately needed to save endemic arthropods in Hawaii.
Some argue that male domination is the natural order of things. However, our genetic relatives, bonobos, who share nearly 99% of our DNA, challenge this notion.
Bonobos are great apes living in a society where women dominate, a rarity among mammals, especially those where males typically hold more power. Despite being smaller in size, female bonobos are the leaders in their society.
A recent study published in the Journal Communications Biology sheds light on how female bonobos acquire and maintain power within their communities. Researchers found that females form coalitions with males, creating a favorable power balance.
When a male bonobo challenges the status quo, nearby females band together to confront or intimidate him. This results in the male losing social rank, which is then transferred to the female aggressor, providing better access to resources and protection for her offspring.
Bonobos and chimpanzees are our closest living relatives. Initially believed to be a subspecies of chimpanzees, they were recognized as a separate species over a century ago. These endangered apes are primarily found in the Democratic Republic of the Congo and are challenging to study in their natural habitat.
To conduct their research, scientists like Harvard University’s Martin Surbeck spent thousands of hours navigating the dense jungle to observe these apes.
Contrary to the peaceful image often associated with bonobos, researchers have noted instances of aggressive behavior within their communities. These findings challenge previous stereotypes about these primates.
Gender conflicts are not uncommon among bonobos. Observations from researchers who tracked conflicts between males and females between 1993 and 2021 show that females often collaborate to assert dominance.
These conflicts can turn violent, resulting in severe injuries and even death for the males involved. The power dynamics within bonobo society have been a subject of interest for scientists for decades.
By studying data collected over years, researchers have found evidence supporting the “female coalition hypothesis,” shedding light on how female bonobos maintain power and influence in their communities.
As research continues to unveil the complexities of bonobo behavior, it becomes increasingly crucial to protect these endangered species.
Bonobos serve as a mirror to humanity, offering insights into our evolutionary past. Preserving these remarkable creatures is essential for understanding our own origins.
The study challenges the notion of male domination as an intrinsic biological trait, highlighting the unique social structures observed in bonobo communities.
Dr. Sarbeck emphasizes that patriarchy and male dominance are not evolutionary imperatives, as exemplified by the social dynamics of bonobos.
After protests from scientists and health experts, federal health officials said Thursday it would restore funding for the Women’s Health Initiative, one of the largest and longest research into women’s health to date.
The discovery of WHI and its randomized controlled trials has helped to change medical practices, form clinical guidelines, and prevent hundreds of thousands of cardiovascular diseases and breast cancer.
“These studies represent important contributions to our better understanding of women’s health,” said Emily G. Hilliard, a spokesperson for the Department of Health and Human Services.
“We are currently working to fully recover funding for these important research efforts,” she added. The National Institutes of Health is deeply committed to advancing public health through rigorous gold standard research and is taking immediate steps to ensure the continuity of these studies.”
Researchers hope to use the findings to learn more about how to maintain mobility and cognitive function and slower memory loss, detect cancer faster, and predict risks for other diseases.
HHS notified research team leaders that it would end the contract for WHI’s regional center in September, but the clinical coordination center based at Fred Hatch Cancer Center in Seattle will be funded until at least January 2026.
Sen. Patty Murray, a Washington Democrat, said shutting down the trial would be “a catastrophic loss for women’s health research.”
Not only has the initiative led to significant advances in women’s health, it also “paved the way for a generation of researchers focused on women’s health. This has been overlooked for a long time and underfunded,” Murray said.
WHI includes many randomized controlled trials, contributing to over 2,000 research papers. However, it is perhaps best known in a study of hormone replacement therapy that suddenly stopped in 2002 after researchers discovered that older women who collected estrogen-progestin combinations experienced a small but significant increase in their risk of breast cancer.
Until then, there was a widespread belief that hormone replacement therapy would protect women from cardiovascular disease. However, the trial found that women were at increased risk of heart attacks, strokes, and clots, despite the combination of hormones reducing colorectal cancer and hip fractures.
Dr. Joan Manson, one of the long-term lead researchers in the study and one of the medical professors at Harvard Medical School and Brigham and Women’s Hospitals, called the announcement of the funding cuts “sadly.”
She was given a statement by National Health Secretary Robert F. Kennedy Jr. about the importance of reducing chronic illnesses in America, and the original decision to cut funds is baffling, she said.
“There is no good example of the scientific impact of research on chronic disease prevention than WHI,” Dr. Manson said.
Lessons learned Hormonal research has resulted in huge savings Researchers discovered this at medical expenses. One study found that between 2003 and 2012, roughly $35 billion was the number of cases of cancer and cardiovascular disease that were avoided. For every dollar spent on WHI, I saved $140.
One randomized trial conducted by WHI saw the effects of a low-fat diet high in fruit and vegetables. Researchers initially found a reduction in ovarian cancer alone, but long-term follow-up showed that this diet also reduces deaths from breast cancer.
Another study of calcium and vitamin D found that supplements provided slight benefits to maintain bone mass and prevent hip fractures in older women, but did not prevent other fractures or colorectal cancer.
Although the findings have affected medical guidelines, we do not currently recommend that all women take supplements regularly.
Participants in the initiative are currently between 78 and 108 years old, and some scientists have acknowledged that there could be discussions to end the trial. However, careful planning is usually given to shut down such a large-scale wide range of research.
“There’s still a lot to learn,” said Garnet Anderson, senior vice president and director of the Department of Public Health Sciences at the Fred Hatch Cancer Center and lead researcher at the initiative.
“Studying 13,000 women at age 90, what are your health needs? How do you live such a long, healthy life?” she said. “I want to know the secrets of success for healthy aging.”
Part of the reasons research began in the 1990s was the lack of information and research on women’s health and there was little evidence underlying clinical recommendations, says Marian Neuhauser, who heads the cancer prevention program at the Fred Hatch Cancer Center and chairs the WHI steering committee.
“Women are half the population,” Dr. Neuhouser said. “However, they were not included in the study. It was mostly male and the results were extrapolated to women.”
President Trump has ordered the US government to take a major step towards mining vast areas below the sea. This is a move opposed by almost every other country, taking into account international waters from international waters for this type of industrial activity.
The executive order, signed Thursday, will circumvent a decades-old treaty ratified by all major coastal states except the United States. This is the latest example of the Trump administration’s willingness to ignore international institutions, and is likely to spark protests from American rivals and allies.
The order “establishes the United States as a global leader in submarine mineral exploration and development within and outside the national jurisdiction.” Text released by the White House.
Trump’s order directs the promotion of mining permits in both the National Maritime and Atmospheric Administration’s international waters and US territory.
Part of the seabed is covered with potato-sized nodules containing valuable minerals such as nickel, cobalt and manganese. These are essential to advanced technologies that the United States considers to be important to economic and military security, but its supply chain is increasingly controlled by China.
No commercial scale submarine mining has been carried out to date. The technical hurdles were high and there were serious concerns about the environmental impact.
As a result, in the 1990s, most countries agreed to join independent international submarine authorities that dominate the seabed mining of international waters. The Trump administration is relying on the US as it is not a signator The vague 1980 law This allows the federal government to issue submarine mining permits in international waters.
Many countries want to see undersea mining become a reality. But so far, it has been that economic orders should not take priority over the risk that mining could damage fisheries and marine food chains, or that it could affect the essential role of the ocean in absorbing carbon dioxide that warms the planet from the atmosphere.
Trump’s order comes after years of delays at the ISA in setting up a regulatory framework for undersea mining. Authorities have not yet agreed to the set of rules.
The executive order paves the way for metal companies, a well-known undersea mining company, to receive the first permission from NOAA to actively mine. A public company based in Vancouver, British Columbia It was disclosed in March It would ask the Trump administration to approve it through a US subsidiary to mine in international waters. The company has already spent more than $500 million on exploratory work.
“We have production-ready boats,” Gerald Baron, the company’s chief executive, said in an interview Thursday. “We have the means to process materials in friendly partner nations of the Alliance. We are missing out on permission to allow us to start.”
In anticipation of mining as a final allowance, companies like him have invested heavily in developing technologies to mine the seabed. They include a ship with huge claws that stretch to the seabed, and a self-driving vehicle mounted on a giant vacuum cleaner that scrutinizes the bottom of the ocean.
Some analysts have questioned the need to rush towards submarine mining, given the current excess of nickel and cobalt from traditional mining. Furthermore, manufacturers of electric vehicle batteries, one of the main markets in metals, are heading towards battery designs that rely on other factors.
Nevertheless, the projection of future demand for metals generally remains high. And Trump’s escalating trade war with China threatens to limit America’s access to some of these important minerals. These include rare earth elements that can also be found in trace amounts of submarine nodules.
US Geological Survey It is estimated Nodules in a single belt of the Eastern Pacific, known as the Clarion Kriparton Zone, contain more nickel, cobalt and manganese than all ground reserves combined. The area in the open ocean between Mexico and Hawaii is about half the size of the continent of the United States.
The Metals Company’s contract site is located in the Clarion-Clipperton zone, with the oceans averaged around 2.5 miles deep. The company will first apply for exploitation permission under the 1980 law.
China has successfully launched three astronauts into space as part of the crew replacement mission for China’s Tiangong space station, marking another milestone in the country’s aspirations for manned missions to the moon and Mars.
The Shenzhou 20 spacecraft lifted off as scheduled at 5:17pm (0917 GMT) atop China’s Long March 2F rocket, set to arrive at Tiangong after approximately 6.5 hours.
The rocket launched from a facility near the Gobi Desert in northwestern China, and the spacecraft will remain in space until it returns the current crew back to Earth.
Tiangong, also known as the “Celestial Palace” space station, is a Chinese-built station that positions China as a significant player in space exploration after being excluded from the International Space Station due to US national security concerns. China’s space program is overseen by the People’s Liberation Army, a military branch of the ruling Communist Party.
There are concerns about China’s potential use of technology onboard the space station to interfere with satellites and other spacecraft in times of crisis.

Since sending its first astronauts into space in 2003, China has made significant strides in its space program, becoming the third country to do so. It has also landed explorers on Mars and the far side of the moon, with plans to land humans on the moon by 2030.
The Shenzhou 20 mission is led by astronaut Chen Dong, on his third spaceflight, accompanied by fighter pilot Chen Zonglui and engineer Wang Ji. Unlike previous crews, the Shenzhou 20 mission consists entirely of male astronauts.
The incoming crew will replace the current astronauts on board the Chinese space station, staying onboard for approximately six months, like their predecessors.
Scheduled to reach Tianong after 6.5 hours, the spacecraft was launched into space atop the Chinese Long March 2 rocket at 5:17pm on March 2.
The current crew was sent last October and spent 175 days in space. They are set to return on April 29, following a brief overlap with the incoming crew. Tianong, completed in October 2022, has a capacity of up to six people.
During their mission, the astronauts will conduct medical and technological experiments, perform spacewalks for maintenance tasks, and install new equipment, as announced by the Manned Space Agency.
Bone collector caterpillar from the Waianae Mountains of Oahu, Hawaii
Daniel Rubinov et al. 2025
The newly described “Bone Collector” caterpillar species disguises itself as dead insect body parts, allowing them to live in spiders and poach their prey. This is the only caterpillar known to use such a scary camouflage or have a roommate-like spider, a carnivorous animal and a booty cannibalism.
Daniel Rubinoff At the University of Hawaii, Manoa and his colleagues discovered a caterpillar while hiking the Waianae Mountains of Oahu over 20 years ago. They were looking for other species in the same genus, Low mass tumorAlso known as the Hawaiian Fancy Case Caterpillar. “I saw this little, tiny sac covered in a bit of a bug and honestly, I didn’t know what it was,” Rubinov says. “Then we’ll get it back [to the lab]and we realize there is a bit of a caterpillar there.
Newly described species of Low mass tumor – Has not yet received the scientific name – lives in a co-neck inside the trunk of a tree, among rocks and other enclosed spaces. It is the length of its claws and feeds on insects trapped in spider nets. “Only 0.13% of all caterpillars on the planet are carnivorous,” says Rubinoff. “That’s why it’s very difficult for caterpillars to evolve to eat meat.”
Bone collectors avoid becoming the prey itself in creepy ways. Decorate the silk case with fragments of dead insects and molted exoskeletons of spiders. Before disguising it, the creature carefully sizes each body part that may contain the ant’s head, beetle’s abdomen, or fly wings.

“It’s probably the only way to survive with the spider, by covering yourself with the skin of the spider’s own shed and small pieces of past meals,” says Rubinov. This will make the caterpillars smell and taste more like garbage bags than juicy snacks for Arknido Housemates. After about 2-3 months it transforms into moth, smaller than the grain of rice.
If bone collectors are not fully accessorized, this caterpillar is also a cannibal. Researchers learned this after placing two larvae in the same cage, leading to one larger bet for smaller, weaker siblings. This is why only one bone collector is displayed per Spider Web, says Rubinoff.
Researchers have discovered only 62 of these creatures over more than 150 field studies conducted over approximately 22 years.
Genetic analysis shows that the lineage is more than 3 million years old than Oahu, meaning it was once again spreading. “Since humans arrived in places like this, we have lost many native species,” says Rubinoff. “Both we were able to find is a miracle [the bone collector]and it’s really sad that they are so restricted to this one place.
woman Bonobos New research is discovering that they team up to find strength in numbers and combine them to dodge wild men.
With ChimpanzeesBonobo is one of the closest relatives of humans. Scientists have been wondering why bonobos live in general Women dominate Men are physically bigger and stronger, so they are social.
30 Years of Observation in the Congo – The only place where endangered bonobos are seen in the wild is to support the idea of sisters who unite to assert their powers.
These groups of girls found women who ousted male bonobos out of the trees, secured food for themselves, and ranked them higher on the community’s social ladders, researchers found.
“It’s very clear not to step on as a male bonobo,” said Martin Sarbeck, Harvard research author.
The findings were published in the Journal Communications Biology on Thursday.
The combined number of female bonobos appears to change the tide to male fitness, Sarbeck said. This type of strategy allows women to get women to top the top in the Animal Kingdom. Find power in the group as well.
Female bonobos linked, even if they had no close relationships, supported each other against men, and solidified their social status. The observations show how female bonobos work together to protect themselves from male violence, bioanthropologist Laura Lewis said at the University of California, Berkeley.
The findings “support the idea that humans and our ancestors use coalitions to maintain and maintain power over millions of years,” Lewis, who was not involved in the study, said in an email.

A new kind of microscope?
Science is one of the most fruitful sources of new terms. There are conditions such as “mitochondrial integration” and “quantum fluctuations” and there is no way to make sentences reliable.
Recently, there have been various scientific papers that contain the phrase “.”Nutrition Electron Microscope/Microscope“The term suggests a device for scanning broccoli, but it is completely nonsense. There are scanning electron microscopes and tunneling electron microscopes, but there are no nutritional electron microscopes.
One possible explanation was proposed by Alexander Magazinov, a software engineer who illuminates Moonlight as a watchdog for Science Publishing. He pointed to Article from 1959 in Bacteriological reviewthe text was formatted into two columns. 4 To the bottom of the pagethe words “nutrition” and “electron microscope” appear next to each other in the left and right rows. Older papers are often scanned using optical character recognition, but such software can be a pain to deal with complex formats. “Nutritional electron microscope“According to the magazine, it is “artificial for text processing.”
But the journalist on Retraction Watch I discovered another possibilitythat was it Reddit has been flagged. In Falsi, the phrases “scanning electron microscope” and “nutritional electron microscope” are very similar, and, importantly, they use almost identical letters. The only difference is a single dot, nuqta. This means that small mistakes in translating paper from Persian to English are sufficient to create a “nutritional electron microscope.”
These explanations are not mutually exclusive, and feedback is satisfied that they can explain the appearance of this phrase. The bigger question is why it lasts in published research. Are these papers not strict? Peer reviews and checksto ensure high accuracy and therefore maintain the integrity of the scientific literature? Perhaps such “tortured phrases” should be included in the checklist of warning signs that the paper may be plagiarized or fraudulent.
Readers who encounter similar tortured phrases during their viewing of technical literature are invited to submit them to their regular address.
The nun is too far away
Sometimes feedback can receive stories that feel so good. The setup is so clean and the rewards are amazingly inevitable at the same time, so we doubt ourselves. Is the reality very beautiful? And we remember that the Titanic faction was the largest ship ever on that maiden voyage when it was built and when bad things happened. Sometimes reality is melodramatic. So, I believe this story happened as explained, but it may not be.
Come to us from Charlie Watnaby. The late Father John, Charlie Watnaby, was a curator at the Science Museum in London. It is inevitably related to the issue of Scunthorpe. The difficulty of banning offensive words in online discussions when strings of the same letters can appear in harmless words such as “peacock” or “sussex.”
John’s story is, technically speaking, not an example of Scunthorpe’s problem, but it definitely contiguous to it. As Charlie explains, “On the early days of the Computing Gallery, machines were set up so that the public could enter their own words and see them on the big screen.
This may seem like an invitation to misconduct. Therefore, readers will be pleased to know that staff expect an inevitable attempt to write a torrent of filth on a big screen so that everyone can see. They drew a “long list of blasphems,” all of which were blocked.
“Everything was going well,” says Charlie, until the system was defeated by the most dangerous person possible: the computer expert. While trying to use the machine, he realized that some keystrokes did nothing. “After investigating, he was able to pull up the entire list of offence (or offensive) words on the big screen so that everyone could see.
Feedback is prepared to believe in 90% of this story, but in the absence of independent verification, it draws a line to the nun. But we are willing to do wrong about this too. If the abbey schoolchild was at the science museum on that fateful day, and if you think you remember, contact us.

Tabular icebergs are away from Antarctica ice shelves
James Kirkham
When the ice sheets covering much of Northern Europe were rapidly retreating about 18,000-20,000 years ago, urban-sized icebergs once drifted through the British coast.
James Kirkham During a survey in the Antarctic of England, his colleagues discovered preserved scour marks created by these giants, which were created when they ploughed underwater sediments. The long comb-like features are buried under the mud of the North Sea, but are still visible in seismic survey data collected for searches for oil and gas.
“We know about the degree of scouring and ancient sea level, so we can estimate that these bergs are probably five to tens of kilometers wide, and perhaps hundreds of meters thick.
In Antarctica, table-form or table-top icebergs are a spectacular sight. Some will rival even small states in the US from a regional standpoint, like the recent giants known as the A23A and A68A. They listen from the ice shelf – a wide floating protrusion of a glacier flowing from the glacier.
Therefore, the perception that tabular icebergs once existed in the North Sea clearly shows that they had both the sea edges of the British and Ireland ice sheets and ice shelves. And that means there may be some lessons for the future decline of Antarctica, says Keycam.
In the North Sea, the large iceberg’s straight trams are written by wavy valleys made by narrow keels of much smaller blocks of ice. In other words, there is a “change of administration” in which large icebergs are replaced by countless small icebergs when ice shelves are crushed in response to rising temperatures, says Keekam.
Radiocarbon dating of sediments indicates that this shift occurs between 20,000 and 18,000 years ago.
Observations question the idea that labours of megabergs like the A23A and A68A may signal the widespread collapse of Antarctic ice shelves.
Emma Mackey The University of Florida tracks tabular iceberg sizes with satellite data since the mid-1970s, finding this trend to be inherently flat.
“James’ research highlights the mines, which means that major birth events are not necessarily signs of instability or cause of alarm,” says McKee. “In fact, ice shelves are disintegrated by death by 1,000 cuts. You need to worry when you stop watching large-scale birth events.”
African farmers who produce some of the world’s most respected coffee are scrambling to comply with the new European Union environmental regulations, which require that the origins of any shipping of beans be documented.
The new measures, which will come into effect at the end of this year, are designed to prevent deforestation driven by agriculture expansion. To comply, farmers need to provide geographical data to show that no coffee is being grown on land where forests have recently been cut down.
Producers are unable to lose access to the vast European markets since December 31st.
Europe consumes more coffee than any other country in the world, and experts say the new regulations, officially known as the EU deforestation regulations, are potentially powerful tools to promote sustainable agriculture and prevent deforestation.
But it also represents what we call the “green squeeze,” which places a heavy burden on millions of small farmers in developing countries that are least contributing to climate change, testing the ability of policymakers to balance people’s needs with natural needs.
“Of course, data is very important to us, but what we’re saying is that we need support,” said Degen Daddy, head of the Oromia Coffee Farmers Co-op. “It’s very challenging and expensive and there’s no help for us.”
Dadi said his group, Ethiopia’s largest cooperative of coffee growers, has more than half a million members based in the central part of the country and could not prepare all the farms by the deadline, possibly without additional support.
Trainers have been crossing the Oromia region for over a year, collecting map coordinates and assisting farmers with new technology. As of March, they were mapping 24,000 farms. European officials validate shipments by cross-checking current geographical allocation data against baseline satellite images and forest cover maps.
Daddy said the cost of mapping one farm is about $4.50. The cost of training is partially covered by grants from the International Trade Centre, a joint organisation of the United Nations and the World Trade Organization, established to help poor countries expand their trade.
Ethiopia is the top coffee producer in Africa, with crops accounting for around 35% of the country’s revenue. The Arabica variety is smooth and gentle with fruity, nutty notes, and comes from the country’s southwest highlands. Over a third of Ethiopian coffee is sent to Europe.
Last year’s French government report says EU consumption is liable 44% of coffee-related deforestation all over the world. Another report by the Environmental Group, World Resources Research Institute, found that there was about 2 million hectares of forest cover Replaced with a coffee farm Between 2001 and 2025. Indonesia, Brazil and Peru recorded some of the highest deforestation rates in that period.
The global leader pledged in 2021 at Glasgow Climate Summit to end deforestation by 20303. The agreement highlighted a growing awareness of nature’s role in tackling the climate crisis. The intact forests are natural reservoirs of carbon that warm the planets, keeping them away from the atmosphere. As carbon dioxide, trapping the heat of the sun increases global warming. Once the forest is cleared, these areas will switch to greenhouse gas emissions. Additionally, by destroying habitats, it harms the biodiversity of forests and its diversity.
The new EU regulations also cover cattle, cocoa, palm oil, rubber and other crops. Shipment of coffee without proper mapping data can be denied or confiscated and can be fined on the importer.
However, some experts say the measure is being implemented without the necessary support for farmers.
Jodie Keane, an economist at ODI Global, a London-based research organization, said the European Union and major coffee chains should do more to help smallholder farmers.
“We all want to prevent deforestation,” Keene said. “But when applying that standard to rural producers, you need to provide a lot of outreach, sensitization. You need to invest in learning how to do things differently so that they don’t drop them out of the supply chain.”
This was reflected by Etelle Higonet, founder of the watch group Coffee Watch. “These are some of the richest companies in the world,” she said of the European coffee chain. “Of course they could afford to do this.”
In an email, Johannes Dengler, managing partner of Alois Dallmayr, one of Germany’s most well-known coffee brands, confirmed that the new rules are a “big challenge” for Ethiopia. He said Dallmayr is developing a system to ensure compliance and is “working closely with his partners to find viable solutions.”
The Director-General of the European Union’s Trade and Economic Security did not respond to a request for comment. in News Release on April 15th Based on feedback from partner countries, the bloc said it allocated 86 million euros, or about $97 million, to support compliance efforts.
Ethiopian coffee farmers take pride in their high quality beans, as a result of exceptional heirloom varieties, highlands and traditional agricultural practices.
In southwestern Zinma Highlands, farmers like Zinabu Abadura say most growers follow long-standing unwritten rules for cutting trees.
Abadura, who sells directly to informal intermediaries, said his farm has not yet been mapped. Most farmers in his area generate coffee revenue and cannot afford to pay any confusion or additional costs. “Life will be difficult,” he said, as new European rules will be implemented.
However, the new EU standards can sort Ethiopia’s coffee sector, but analysts say they probably won’t stop selling.
Countries like China offer alternative, less isolated markets. And Ethiopia itself is a big coffee drinker. Hospitality is incomplete without a coffee ceremony hosting roasts, grinds and brews in front of guests. About half of the country’s annual coffee production stays at home.
But Tsegaye Anebo, who heads the Sidama Coffee Union, which represents 70,000 farmers, said the pivot to the new market would be disruptive in the short term. He said that the species of ferns in his area are distinctive in its fruity tone and are a favorite in wealthy Europe. And that means premium prices.
Giving up the EU market is not an option, he said.
“We need the EU,” Anebo said. “But they need us too, because they can’t find our coffee anywhere.”
Last year presented significant challenges for Acadia Healthcare, one of the nation’s leading providers of mental health services.
A New York Times investigation in September revealed that multiple federal agencies were looking into accusations of Acadia unlawfully detaining patients in mental health hospitals. This led to a sharp decline in Acadia’s stock value and rattled investors.
Despite these troubles, Acadia’s CEO, Christopher Hunter, benefitted from the situation. As indicated in the recent financial report, he received a $1.8 million bonus from the board to deal with the “unprecedented government inquiries.” This bonus was on top of his regular compensation, exceeding $7 million in 2024.
Other top executives at Acadia, including the CFO and Legal Advisor, also received substantial bonuses, with the COO promised a bonus as well. These bonuses were given to prevent key leaders from leaving before the investigation was concluded, according to Acadia.
The board of directors at Acadia believed that retaining the current leadership team was in the best interest of the company, its patients, and communities. They emphasized the use of peer market data for evaluating performance and benchmarking.
The Times investigation uncovered that Acadia had been holding patients against their will to maximize insurance payments. This practice had started before Hunter took over as CEO in April 2022 but continued under his leadership.
Following the allegations, Acadia stated that they would vehemently deny fraud and cooperate with the investigation. Hunter assured investors that the claims of holding patients longer than necessary were false and contradicted their commitment to patient care.
After the investigation was initiated, Acadia disclosed that various government agencies, including the Department of Justice and the Securities and Exchange Commission, were investigating the matter. Additionally, shareholders filed a class action lawsuit against the company, accusing them of withholding information from investors.
Issues were also uncovered in other areas of Acadia, such as a methadone clinic overbilling the government for services not rendered. Inadequate staffing levels at one of the company’s women’s facilities led to tragic incidents, as reported by The Times.
Since September, Acadia’s market value has plummeted by approximately $5 billion, now valued at around $2 billion.
Hunter’s compensation is tied to Acadia’s stock performance, but the company’s stock decline in 2024 caused him to miss his targets. Critics, like Sarah Anderson from the Institute of Policy Research, argue that linking compensation to stock prices can incentivize risky behavior and undermine performance.
In Roman arenas, gladiators fought lions and other wildlife. Despite the tales of epic battles found in ancient texts, sculptures, mosaics, and portrayed in modern media, physical evidence of gladiators with animal-inflicted wounds has never been discovered by archaeologists.
Recently, skeletal remains from Roman settlements in the UK provided the first direct evidence of gladiators who were injured by lions.
The discovery was made during excavations in York, where a couple was planning to renovate their garden. The cemetery found at the site halted construction plans and revealed a rich Roman archaeological history in the region.
Tim Thompson, an anthropologist from Maynooth University and author of a paper published in the journal PLOS One, highlighted the significance of this discovery in shedding light on ancient Roman practices.
The site in York contained the remains of over 80 individuals, mostly young men with signs of trauma on their bodies. The demographics, injuries, and burial practices suggest that these individuals were gladiators who fought in the area nearly 1,800 years ago.
One particular skeleton, identified as 6DT19, displayed a unique wound on its hip bone that resembled bite marks from a large animal, possibly a lion.
Further analysis indicated that the injuries on the skeletons could indeed be bite marks from large animals like lions. This finding challenged previous beliefs about the absence of physical evidence of gladiators fighting animals.
Dr. Thompson and his team collaborated with British zoos to study animal bite marks and compare them to the skeletal injuries found on the ancient remains.
Through meticulous analysis and comparison, they concluded that the injuries on the gladiators matched those inflicted by lions. While the bite on 6DT19 likely did not cause death, it provided valuable insights into the practices and culture of the Roman Empire.
This discovery not only sheds light on individual lives from the past but also reveals the extent of Roman influence and entertainment involving gladiator battles with animals.
Dr. Marklein, an anthropologist from the University of Louisville, emphasized the significance of these findings in understanding Roman society and its use of violence as entertainment and political display.
Gladiator games served not only as spectacles of power but also as warnings and demonstrations of Roman citizenship and virtue.
This discovery underscores the complex relationship between humans, animals, and culture in ancient Rome.
A year later, Vermont enacted the Climate Change Superfund Act, holding an oil and gas company financially responsible for the state’s climate damages. A similar law was passed in New York in 2024 and is pending in California, Maryland, and Massachusetts.
Understanding the law involves attribution science, a field that uses global temperature data to model numerous scenarios to determine if extreme weather events like floods and heatwaves are linked to emissions from burning oil, gas, and coal.
A new paper published in Nature Journal on Wednesday magnifies this work to connect emissions from specific entities to the economic impact of extreme events.
“The oil industry is astonished by the state’s climate superfund laws and their increasing popularity, as they are the first policies globally to hold a significant portion of the major losses responsible for the substantial damages incurred by their products.”
The response to the law was swift. In February, West Virginia and other Republican-led states sought to challenge New York’s laws, arguing that only the federal government has the authority to regulate emissions. President Trump signed an executive order this month criticizing the state law as a burden and ideological motivation, calling on Attorney General Pam Bondy to block enforcement.
Environmental attorneys have been exploring how harm can be attributed to greenhouse gas emissions for years, according to Martin Rockman, a climate law fellow at Columbia University’s Sabine Center.
“Attribution science is crucial because it establishes links between particular activities of businesses that profit from fossil fuels and specific harms to states and communities,” Rockman stated. “If you’re causing harm, you should be accountable for mitigating it, it’s that simple.”
The new study will enhance an approach known as “end-to-end” attribution, linking a specific emitter (e.g., a company) to a particular climate-related impact (e.g., extreme heat) and subsequent damage (impact on the global economy).
The study revealed that Chevron’s emissions caused heat-related losses totaling up to $3.6 trillion in the global economy. Christopher Callahan, a postdoctoral geoscientist at Stanford University and the study’s author, noted that such high costs still underestimate the global repercussions of fossil fuel combustion in less affluent tropical regions with minimal emissions responsibility.
“That astounding figure represents the detriment from just one of the climate impacts,” stated Delta Melner, associate director of the Science Hub for Climate Litigation at the Coalition of Concerned Scientists. “The overall harm caused by major emitters is undoubtedly much greater when considering the full range of climate risks.”
Theodore J. Bootras Jr., a Chevron Corporation lawyer, argued that the study “disregards the scientific impossibility of attributing a specific climate or weather phenomenon to a particular country, company, or energy consumer.” He labeled it as futile state litigation and a misleading advocacy campaign for energy penalties and regulations.
Overall, the paper estimated that the global economy would suffer $28 trillion in damages due to extreme heat caused by emissions from 111 major carbon producers between 1991 and 2020.
More than 100 climate-related lawsuits have been filed annually since 2017, as per a recent study. However, these cases scrutinize attribution studies that struggle to connect emissions to estimated economic losses.
This innovative framework can offer similar capabilities in other major damage and liability cases, analogous to those handled in tobacco-related lung cancer lawsuits and pharmaceutical claims for addiction.
Justin Mankin, a geography professor specializing in climate science at Dartmouth University and co-author of the Nature paper, remarked:
World Weather Attribution, a group based at Imperial College London, has regularly published attribution reports over the past decade.
“Unfortunately, we are still one of the few entities engaged in this work, and we are not an official institution. It’s essentially a project I undertake as a university professor in collaboration with a team of colleagues,” stated Friedrike Otto, a physicist aiding in attributing global weather.
Dr. Callahan and Dr. Mankin utilized open-source tools in their models, developing code and data resources they deployed to publish the global costs of climate change on their website.
“We advocate for transparent and open science, particularly since the research was funded by U.S. taxpayers,” Dr. Mankin emphasized, highlighting a significant portion of the research support originating from NOAA, the nation’s leading climate science agency facing funding cuts during the Trump administration.
Extreme weather events have disrupted communities and continue to exacerbate tensions. According to Vermont Senator Anne Watson, the 2023 flood cost Vermont hundreds of millions of dollars, prompting her to sponsor a bill quantifying state damages between 1995 and 2024.
Julie Moore, the secretary at the Vermont Natural Resources Agency, assisted states in organizing their inquiries for more information to better grasp the various approaches in attribution science and comprehend how to assign damages caused by greenhouse gas emissions.
“The charge against us is to establish guidelines on applying attribution science and ultimately send out a cost recovery notice,” Moore explained. According to state laws, oil and gas companies will receive this notice in early 2027.
“The expectation is that it will aid Vermont in securing a substantial amount to cover damages and adapt to a hotter, more humid climate resulting from carbon in the atmosphere,” Watson expressed. “We need a source to determine accountability for this.”
Amidst the Trump administration’s focus on declining US fertility rates, recent data from the Centers for Disease Control and Prevention indicates that births remained relatively stable in 2024, increasing by 1% compared to the previous year.
In the United States last year, there were 3,622,673 births, according to a CDC report published on Wednesday. From 2015 to 2020, births experienced an average annual decline of 2%, with fluctuations in subsequent years.
The report also outlines the birth rates for women aged 15 to 44, known specifically as the birth rate. This rate declined between 2014 and 2020, fluctuating until 2024, where it reached 54.6 births per 1,000 individuals—an increase of 0.2% from 2023.
Brady Hamilton, the primary author of the report and a CDC statistician, noted that the data continues the ongoing downward trend in teenage births and the upward trend in births among older women observed in the past three decades. However, the CDC refrained from offering specific explanations for this trend.
An analysis of CDC data by a sociologist suggests that this trend largely reflects women delaying childbearing in their 20s and opting to do so in their 30s and 40s. Birth rates increased last year among women aged 25 to 44, while declining in teenagers and individuals under 25.
“There are various factors at play,” explained Karen Benjamin Guzzo, director of the Carolina Population Center at the University of North Carolina, Chapel Hill. These factors include considerations about partners, financial stability, job security, and overall expenses.
According to a CDC report, the average woman in 2024 had one or two biological children compared to three or more in 1960. Since 2007, overall birth rates in the US have been decreasing, with sociologists anticipating this trend to persist despite a slight increase last year.
Sarah Hayford, director of Ohio State’s Institute of Population, highlighted that economic improvements post-Great Recession have not necessarily translated into enhanced financial conditions for many individuals, impacting decisions around childbearing.
Guzzo noted that the Trump administration’s policies, including tariffs and federal programs supporting women and children, could impact the environment for childbearing decisions. The administration has expressed concerns over declining fertility rates, with Vice President JD Vance advocating for increased births in the US.
President Donald Trump himself has championed family formation, signing an executive order to expand access to in vitro fertilization. The administration is reportedly considering incentives, such as a $5,000 cash bonus after birth, to encourage more births, although experts suggest these efforts may not reverse declining fertility rates.
Sociologists opine that low fertility rates are not inherently problematic, and the decline in teenage birth rates is viewed as a positive trend. Guzzo expressed optimism that individuals today have more autonomy in deciding the right time for childbearing.
Antibiotics commonly used to absorb pneumonia remove Lyme disease mice at doses 100 times lower than standard antibiotic therapy. This small dose was combined with the targeted effect of the drug on infection, meaning that the animal’s gut microbiota was largely unaffected.
Lyme disease is caused by bacteria in the genus Borelia It spreads mostly among birds and small rodents, but people can get infected via the bites of mites that have given the blood of such animals. Infections generally lead to flu-like symptoms and a “bull” rash. Without treatment, it can cause serious long-term complications such as fatigue and pain.
Standard treatment involves taking the antibiotic doxycycline twice daily at high doses for up to three weeks. This will stop the production of the proteins needed for bacteria to survive, but will not selectively target them Borelia seed. “It will cause chaos normally [gut] It says microbiome. Brandon Footlas At Northwestern University, Illinois.
Looking for a more selective alternative, Jutras and his colleagues first tested how effective it is to have more than 450 antibiotics all approved by the US Food and Drug Administration. Borrelia burgdorferi – The most common type of lab dishes that causes Lyme disease.
They then evaluated how best-performing drugs affected the growth of harmless or beneficial bacteria commonly found in people and mouse visceral organs, such as certain strains. E. coli. This revealed that piperacillin is associated with penicillin, commonly used in the treatment of pneumonia and is the most selective target. B. burgdorferi.
Next, the researchers injected 46 mice. B. burgdorferi. Three weeks later, they treated the animals with various doses of either doxycycline or piperacillin for a week. The researchers found that mice received either high doses of doxycycline or 100 times lower doses of piperacillin, with no signs of infection.
They also analyzed stools from mice before and after antibiotic treatment and found that low doses of piperacillin had little effect on bacterial levels. B. burgdorferi In the gut, high doses of doxycycline significantly altered the gut microbiota.
This is probably due to the low amount of antibiotics, which has less impact on intestinal microbial diversity and is the target action of piperacillin. “We found that using piperacillin is targeting certain proteins. B. burgdorferiit is very efficient to kill this Lyme disease agent at low concentrations, not other bacteria, to survive,” says Jutras.
But mice can respond differently to antibiotics than people, John Ocotte at Johns Hopkins University in Maryland. For example, they often break down the drug faster, which can change its effectiveness. The Jutras team hopes to test piperacillin in human Lyme disease tests in the coming years.
Peanuts are one of the most common foods that people have allergies
naafterphoto/shutterstock
Adults with peanut allergies reduced the risk of a reaction by eating small peanut proteins every day as part of their trials. This approach has already been approved in the US for children with this condition.
Peanut allergies occur when the immune system mistakenly identifies legume proteins as threats. It reacts by producing more IgE antibodies. This is an important part of the immune response, but an allergic reaction causes overdrive. As a result, inflammation increases, causing symptoms such as swelling, itching, and vomiting. In extreme cases, it can lead to anaphylactic shock, a life-threatening response that can affect someone’s breathing or heart rate.
Until recently, the only solution was to avoid peanuts, but an intervention called oral immunotherapy was approved in 2020 for children with allergies in the US. This involves exposing the immune system to peanut protein, which gradually increases allergens.
However, it was unclear whether this approach worked in adults as well. “Although most of the life of an individual with a peanut allergy is spent as an adult, there was no treatment that reduced the fundamental reactivity to peanuts,” he says. Stephen Till King’s College London. “There are some grounds for suspecting that adults are more difficult to fall out than children, as your immune system is easy to fix when you’re young.”
To fill this knowledge gap, Till and his colleagues recruited 21 adults with peanut allergies. At the start of the study, participants on average only 1/8 of the peanuts were eaten before they developed an allergic reaction.
The team fed each participant a protein equivalent to one-fourth of peanuts each day for two weeks. This dose increased slightly every two weeks for several months, but was able to safely and consistently eat the equivalent of four large peanuts of protein every day.
Three participants dropped out of the study due to an allergic reaction, while three other participants left for reasons not related to treatment. “This dropout number is acceptable for this type of treatment.” Cezmi Akdis At the Swiss Allergy and Asthma Institute.
The remaining 15 participants participated in an allergy test for eating an increase in peanut protein under the supervision of the researchers. All but one of them were able to eat five peanut equivalents without an allergic reaction.
In another part of the experiment, the team analyzed blood samples collected from participants before and after receiving oral immunotherapy. This revealed that the intervention had high levels of IgG antibodies that counteract the effects of IgE antibodies.
“It’s very promising,” Akudith says. “This approach means that adults with peanut allergies may be relieved of the anxiety of eating peanut-contaminated foods.”
However, this is a relatively early stage test, and a larger test is needed to verify the results and establish how long the protection will last, he says. “I think you need to take peanuts daily or regular over the long term to maintain resistance to allergens,” Aqudith says. “People take pills every day, so I think people affected by peanut allergies are following this type of method.”
Do not try to treat allergies without medical supervision.
There could be a secure quantum internet in the middle

Another step to the quantum internet has been completed and no special communication equipment is required. Two German data centers have already used existing communication fibers to exchange quantum safe information at room temperature. This is in contrast to most quantum communications, and in many cases it requires cooling to very low temperatures to protect quantum particles from environmental disturbances.
Thanks to being encoded into quantum particles of light, known as photons, the quantum internet, which allows for extremely secure exchange of information, is rapidly expanding into the world outside of labs. In March, microsatellites enabled quantum links between China’s ground stations and South Africa. A few weeks ago, the first operating system for quantum communications networks was announced.
now, Mirko Pittaluga Toshiba Europe Limited and his colleagues are sending quantum information through optical fibers between two facilities, approximately 250 km apart, in Kehl and Frankfurt, Germany. This information passed through the third station between them, just over 150km from Frankfurt.
Photons can be lost or damaged when crossing long distances through fiber optic cables, so large quantum internet iterations require “quantum repeaters” and reduce these losses. In this setup, the midway station played a similar role, allowing the network to outweigh the simpler connections between the two previously tested endpoints.
In a notable improvement on previous quantum networks, the team used existing fibers and devices that could be easily slotted into racks that already house traditional communication equipment. This enhances the case where Quantum Internet will ultimately become plug-and-play operations.
The researchers also used photon detectors that cost much less than those used in previous experiments. Although some of these previous experiments spanned hundreds of kilometers, they say that using these detectors reduces both the cost and energy requirements of the new network.

Premkumar Northwestern University in Illinois says that using the types of quantum communications protocols here on commercial equipment highlights how quantum networks are approaching practicality. “Systems engineers can see this and see that it works,” Kumar says. However, he says that in order to be completely practical, networks need to exchange information faster.
Medi Namaji Quantum Communication Start-Up Qunnect in New York says that this approach could be beneficial for future networks of quantum computers or quantum sensors, but it is not as efficient as involving true quantum repeaters.
